From mouse model to human; serendipity leads to human genetic diagnosis

When Dr. Huda Zoghbi and her colleagues were investigating the role protein complex ATXN1-CIC plays in the normal development of the mouse brain they did not expect their work would lead to finding a genetic cause of an undiagnosed human condition. “When we began this research, we were just curious about what the ATXN1-CIC complex normally does,” … Continue reading

ABL1 gene plays a role in cancer and in a developmental disorder

The human gene ABL1 is well-known for its association with cancer. In this case, a piece of chromosome 9 containing the ABL1 gene and a piece of chromosome 22 break off and switch places. The ABL1 gene fuses with the BCR gene in chromosome 22, which is then called the Philadelphia chromosome. Bone marrow cells … Continue reading

Mutations in CWC27 result in spectrum of conditions

Mingchu Xu searches for genes linked to retinitis pigmentosa, a condition of the retina characterized by progressive development of night blindness and tunnel vision, sometimes from the early age of 2. Retinitis pigmentosa is the most common inherited disorder of the retina; it affects nearly 1 in 4,000 people, and more than 1 million are visually … Continue reading

No SOX9, no cartilage; and how DDRGK1 causes a rare human skeletal dysplasia

SEMD, Shohat-type spondyloepimetaphyseal dysplasia, is a rare type of skeletal dysplasia that affects the development of cartilage and results in a form of dwarfism with a particular pattern of joint abnormalities, scoliosis and defects of the long bones. Similar skeletal disorders are linked to mutations in type II collagen (COL2A1) gene, but the gene causing SEMD … Continue reading

A striking number of genetic changes can occur early in human development

Dr. Pengfei Liu has a challenging job.  As the assistant laboratory director of Baylor Genetics and assistant professor of molecular and human genetics at Baylor College of Medicine, he is part of a team of researchers that evaluates young patients with a variety of developmental issues in order to determine the posibility of a genetic diagnosis of their condition. … Continue reading

Image of the Month: Close and personal with bacteriophage P22

For nearly 30 years the laboratory of Dr. Wah Chiu, Distinguished Service Professor and Alvin Romansky Professor of Biochemistry and Molecular Biology at Baylor has been applying electron cryomicroscopy and computer reconstruction techniques to determine the 3-D structures of biological nanomachines, such as the P22 virus. This virus, a bacteriophage that infects Salmonella, has been … Continue reading
