As personalized, genomic medicine takes off, four developing countries show the way for others

Four developing countries are leading the way in establishing domestic capacity for genomic medicine, improving national health, reducing medical costs and bolstering economies. Mexico's program is the most comprehensive, with genotyped over 1,200 people to study genetic relationships with various health problems.

Chromosomal abnormalities play substantial role in autism

A recent study published in the American Journal of Human Genetics reveals that chromosomal abnormalities contribute substantially to autism, with 7% of children carrying unique genetic changes. The researchers identified 13 regions of the genome with overlapping or recurrent chromosomal changes in unrelated individuals with autism.

Study of twins finds genetic link to fatigue

A recent study published in The British Journal of Psychiatry found that genetic inheritance is the main cause of unexplained disabling fatigue in children. The research, conducted at Cardiff University, suggests that familial influences play a significant role in both short- and prolonged-duration fatigue.

Indiana U researchers closer to finding a genetic cause of hearing loss in aging

A study of 50 pairs of fraternal twins with hearing loss identified a specific region of DNA, DFNA18 on chromosome 3, that may contain an important locus for hearing loss in the general population. The findings suggest variation in genes within this region could lead to differences in susceptibility to hearing loss.

Myelin suppresses plasticity in the mature brain

Researchers at Yale University found that myelin physically limits axonal growth and regeneration after traumatic injury. Blocking vision in one eye normally alters ocular dominance only during critical development, but mutations in the Nogo-66 receptor affect abnormal plasticity later in life.

Something old, something new

Researchers Drs Sun and Arceci find that loss of PASG gene results in reduced genomic methylation and premature aging in mice. The study reveals a potential model for studying aging and epigenetic regulation, with implications for cancer predisposition and therapeutic targeting.

Jews are the genetic brothers of Palestinians, Syrians, and Lebanese

A recent study published in the Proceedings of the National Academy of Sciences found that Jewish men share a common set of genetic signatures with non-Jews from the Middle East, including Palestinians, Syrians, and Lebanese. This suggests that Jews and Arabs are more closely related to one another than to non-Jews from other areas of ...

Long-QT syndrome

A Mayo Clinic study found that a genetic defect known as long-QT syndrome may be the cause of many unexplained drownings. The research identified a genetic mutation in a 19-year-old woman who died after a near-drowning, and subsequent testing revealed that her mother and sister also had inherited the condition.
