Gonosome anomaly
MONDO:0020058Chromosomal disorder in which the chromosomal anomaly involves an gonosome. A gonosome is a chromosome responsible for sex determination. In humans and most animals, the sex chromosomes are designated X and Y.
Also known as: Sex-chromosome anomaly

New study aims to unlock mysteries of sex chromosome disorders in children
Knowledge-focused By invitation onlyThis study follows 300 fetuses and children with sex chromosome disorders to track their growth, organ development, and overall health. Researchers will also look at genetic and gut microbiome factors. The goal is to better understand how these conditions affect children over tim…

Scientists probe genetic secrets of lost fetuses to unravel sex chromosome mysteries
Knowledge-focused By invitation onlyThis study looks at fetuses with sex chromosome disorders (like extra or missing X or Y chromosomes) that were either miscarried or electively aborted. Researchers will analyze the placenta and fetal tissues to see how the chromosome changes affect gene activity and development. …
