Chromosome 3 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 3, one copy inherited from each parent, form one of the pairs. Chromosome 3 spans almost 200 million base pairs (the building blocks of DNA) and represents approximately 6.5 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 3 likely contains between 1,100 and 1,500 genes.

Genes on chromosome 3 are among the estimated 20,000 to 25,000 total genes in the human genome.

Molecular pathology of Schaaf-Yang syndrome: Insights into MAGEL2 gene mutations and truncated proteins

Mutations in the MAGEL2 gene, which cause Schaaf-Yan syndrome (SYS) —an ultra-rare disease that affects neuronal and cognitive development— generate truncated, non-functional proteins that tend to accumulate in the cell nucleus.

SCA4 genetic breakthrough: Unveiling the cause of a devastating neurological disease

Some families call it a trial of faith. Others just call it a curse. The progressive neurological disease known as spinocerebellar ataxia 4 (SCA4) is a rare condition, but its effects on patients and their families can be severe.

Research reveals potential target for enfortumab vedotin therapy in urothelial carcinoma

Under the leadership of PD Dr. Niklas Klümper, Assistant Physician at the Department of Urology at the University Hospital Bonn (UKB) and Clinician Scientist of the BMBF-funded ACCENT program and PD Dr. Markus Eckstein, senior physician at the Institute of Pathology at the Uniklinikum Erlangen of the Friedrich-Alexander-University Erlangen-Nürnberg (FAU), an interdisciplinary research team has published new findings that indicate which patients with advanced urothelial carcinoma could benefit in particular from the new targeted therapy with the antibody-drug conjugate enfortumab vedotin.

Research links Y chromosome decline to patrilineal societies

The emergence in the Neolithic of patrilineal social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome observed worldwide between 3,000 and 5,000 years ago.

Timelapse breakthrough: Scientists capture secrets of early embryonic cell division

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells – the cells that have a specialized function, like skin and muscle cells – they remain elusive in the first cells of our bodies, the embryonic cells.

Study explores the effects of ovulation inducing method on embryo quality

Low birth rates have become a serious problem in many developed countries throughout the world, with Japan being a prime example. In Japan particularly, aging and stress have led to a massive rise in infertility, which now affects one in every 4.4 couples.
