The Annual Review of Genomics and Human Genetics, in publication since 2000, covers significant developments in the field of genomics as they apply to human genetics and the human genome. We have particular interest in the areas of genomic technology, genome structure and function, genetic modification, human variation and population genetics, human evolution and, importantly, all aspects of human genetic disease and including individualized medicine.

S<scp>TRUCTURING THE</scp> U<scp>NIVERSE OF</scp> P<scp>ROTEINS</scp> ▪ Abstract High-throughput sequencing of human genomes and those of important model organisms (mouse, Drosophila melanogaster, Caenorhabditis elegans, fungi, archaea) and bacterial pathogens has laid the foundation for another “big science” initiative in biology. Together, X-ray crystallographers, nuclear magnetic resonance (NMR) spectroscopists, and computational biologists are pursuing high-throughput structural studies aimed at developing a comprehensive three-dimensional view of the protein structure universe. The new science of structural genomics promises more than 10,000 experimental protein structures and millions of calculated homology models of related proteins. The evolutionary underpinnings and technological challenges of automating target selection, protein expression and purification, sample preparation, NMR and X-ray data measurement/analysis, homology modeling, and structure/function annotation are discussed in detail. An informative case study from one of the structural genomics centers funded by the National Institutes of Health and the National Institute of General Medical Sciences (NIH/NIGMS) demonstrates how this experimental/computational pipeline will reveal important links between form and function in biology and provide new insights into evolution and human health and disease.

The RASopathies The RASopathies are a clinically defined group of medical genetic syndromes caused by germline mutations in genes that encode components or regulators of the Ras/mitogen-activated protein kinase (MAPK) pathway. These disorders include neurofibromatosis type 1, Noonan syndrome, Noonan syndrome with multiple lentigines, capillary malformation–arteriovenous malformation syndrome, Costello syndrome, cardio-facio-cutaneous syndrome, and Legius syndrome. Because of the common underlying Ras/MAPK pathway dysregulation, the RASopathies exhibit numerous overlapping phenotypic features. The Ras/MAPK pathway plays an essential role in regulating the cell cycle and cellular growth, differentiation, and senescence, all of which are critical to normal development. Therefore, it is not surprising that Ras/MAPK pathway dysregulation has profound deleterious effects on both embryonic and later stages of development. The Ras/MAPK pathway has been well studied in cancer and is an attractive target for small-molecule inhibition to treat various malignancies. The use of these molecules to ameliorate developmental defects in the RASopathies is under consideration.

COMPLEX GENETICS OF GLAUCOMA SUSCEPTIBILITY ▪ Abstract Glaucoma describes a group of diseases that kill retinal ganglion cells. There are different types of glaucoma, and each appears to be genetically heterogeneous. Different glaucoma genes have been identified, but these genes account for only a small proportion of glaucoma. Most glaucoma cases appear to be multifactorial, and are likely affected by multiple interacting loci. A number of genetic susceptibility factors have been suggested to contribute to glaucoma. These factors fit into two broad groups, those affecting intraocular pressure and those important in modulating retinal ganglion cell viability. Defining the complex genetics of glaucoma will require significant further study of the human disease and animal models. Genetic approaches are essential and will be enhanced by recently developed genomic and proteomic technologies. These technologies will provide valuable clues about pathogenesis for subsequent testing. In this review, we focus on endogenous genetic susceptibility factors and on how experimental studies will be valuable for dissecting the multifactorial complexity of their interactions.

Recent Advances in the Genetics of Parkinson's Disease Genetic studies have provided valuable insight into the pathological mechanisms underlying Parkinson's disease (PD). The elucidation of genetic components to what was once largely considered a nongenetic disease has given rise to a multitude of cell and animal models enabling the dissection of molecular pathways involved in disease etiology. Here, we review advances obtained from models of dominant mutations in α-synuclein and LRRK2 as well as recessive PINK1, parkin and DJ-1 mutations. Recent genome-wide association studies have implicated genetic variability at two of these loci, α-synuclein and LRRK2, as significant risk factors for developing sporadic PD. This, coupled with the established role of mitochondrial impairment in both familial and sporadic PD, highlights the likelihood of common mechanisms fundamental to the etiology of both.

Sequence Divergence, Functional Constraint, and Selection in Protein Evolution The genome sequences of multiple species has enabled functional inferences from comparative genomics. A primary objective is to infer biological functions from the conservation of homologous DNA sequences between species. A second, more difficult, objective is to understand what functional DNA sequences have changed over time and are responsible for species' phenotypic differences. The neutral theory of molecular evolution provides a theoretical framework in which both objectives can be explicitly tested. Development of statistical tests within this framework has provided insight into the evolutionary forces that constrain and in some cases change DNA sequences and the resulting patterns that emerge. In this article, we review recent work on how functional constraint and changes in protein function are inferred from protein polymorphism and divergence data. We relate these studies to our understanding of the neutral theory and adaptive evolution.

The Spatial Organization of the Human Genome In vivo, the human genome functions as a complex, folded, three-dimensional chromatin polymer. Understanding how the human genome is spatially organized and folded inside the cell nucleus is therefore central to understanding how genes are regulated in normal development and dysregulated in disease. Established light microscopy–based approaches and more recent molecular chromosome conformation capture methods are now combining to give us unprecedented insight into this fascinating aspect of human genomics.

Hedgehog Signaling and Human Disease Developmental pathways first elucidated by genetic studies in the fruit fly Drosophila melanogaster are conserved in vertebrates. The hedgehog pathway, first discovered because of its involvement in early Drosophila development, plays a key role in human embryogenesis. Dissruption of this pathway has been associated with congenital anomalies of the central nervous system, axial skeleton, limbs, and occasionally other organs. Many developmental genes continue to play an important role in regulation of cell growth and differentiation after embryogenesis, and mutations that lead to activation of the hedgehog pathway result in skin cancer and other malignancies in children and adults.

SULFATASES AND HUMAN DISEASE ▪ Abstract Sulfatases are a highly conserved family of proteins that cleave sulfate esters from a wide range of substrates. The importance of sulfatases in human metabolism is underscored by the presence of at least eight human monogenic diseases caused by the deficiency of individual sulfatases. Sulfatase activity requires a unique posttranslational modification, which is impaired in patients with multiple sulfatase deficiency (MSD) due to a mutation of the sulfatase modifying factor 1 (SUMF1). Here we review current knowledge and future perspectives on the evolution of the sulfatase gene family, on the role of these enzymes in human metabolism, and on new developments in the therapy of sulfatase deficiencies.

H<scp>UMAN</scp> M<scp>IGRATIONS AND</scp> P<scp>OPULATION</scp> S<scp>TRUCTURE</scp>: What We Know and Why it Matters ▪ Abstract The increasingly obvious medical relevance of human genetic variation is fueling the development of a rich interface between medical genetics and the study of human genetic history. A key feature of this interface is a step increase in the size and diversity of genetic data sets, permitting a range of new questions to be addressed concerning our evolutionary history. Similarly, methodologies first developed to study genetic history are being tailored to address medical challenges, including mapping genes that influence diseases and variable drug reactions. In this paper we do not attempt a comprehensive review of human genetic history. Rather we briefly outline some of the complications and challenges in the study of human genetic history, drawing particular attention to new opportunities created by the explosive growth in genetic information and technologies. First we discuss the complexity of human migration and demographic history, taking both a genetic and archaeological perspective. Then we show how these apparently academic issues are becoming increasingly important in medical genetics, focusing on association studies, the common disease/common variant hypothesis, the evaluation of variable drug response, and inferences about gene function from patterns of genetic variation. Finally we describe some of the inferential approaches available for interpreting human genetic variation, focusing both on current limitations and future developments.

Biased Gene Conversion and the Evolution of Mammalian Genomic Landscapes Recombination is typically thought of as a symmetrical process resulting in large-scale reciprocal genetic exchanges between homologous chromosomes. Recombination events, however, are also accompanied by short-scale, unidirectional exchanges known as gene conversion in the neighborhood of the initiating double-strand break. A large body of evidence suggests that gene conversion is GC-biased in many eukaryotes, including mammals and human. AT/GC heterozygotes produce more GC- than AT-gametes, thus conferring a population advantage to GC-alleles in high-recombining regions. This apparently unimportant feature of our molecular machinery has major evolutionary consequences. Structurally, GC-biased gene conversion explains the spatial distribution of GC-content in mammalian genomes—the so-called isochore structure. Functionally, GC-biased gene conversion promotes the segregation and fixation of deleterious AT → GC mutations, thus increasing our genomic mutation load. Here we review the recent evidence for a GC-biased gene conversion process in mammals, and its consequences for genomic landscapes, molecular evolution, and human functional genomics.
