Description
Qin Wang leads a large team that pins, in a 2026 study, a new inherited brain disorder on faults in a chromatin-shaping gene. Chromatin remodelers open and close DNA to time gene activity, and their failure often disrupts brain development. The gene DMAP1 helps run several of those processes yet had no linked human disease. The team gathered 20 affected people from 16 families, each carrying two damaged copies of the gene.
Fruit flies with the matching gene silenced in the brain died early or showed shrunken learning centers, stunted nerve branches, odd social behavior, and seizures. Adding back the healthy human gene mostly rescued the flies, while patient versions rescued weakly or not at all. Two downstream genes emerged whose boost repaired the damage. A chemical fingerprint on DNA then identified one more patient. Genetic testing panels for developmental disorders gain a new entry.
