PHF12

Chr 17

PHD finger protein 12

Also known as: PF1

Enables phosphatidylinositol binding activity and transcription corepressor activity. Involved in negative regulation of DNA-templated transcription. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Located in nucleoplasm. Part of Sin3-type complex and transcription repressor complex.

Gene-Disease Validity (ClinGen)
complex neurodevelopmental disorder · ADDefinitive

Definitive — sufficient evidence for diagnostic panels

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
