FLYWCH1
Chr 16FLYWCH-type zinc finger 1
FLYWCH1 encodes a transcription cofactor that negatively regulates gene transcription and participates in DNA damage response signaling. Mutations cause autosomal dominant neurodevelopmental disorder with developmental delay, seizures, and behavioral abnormalities. The gene is extremely intolerant to loss-of-function variants (pLI ~1.0), indicating that complete loss of protein function is likely incompatible with normal development.
