Genes affected

PHF12 (HGNC:20816): (PHD finger protein 12) Enables phosphatidylinositol binding activity and transcription corepressor activity. Involved in negative regulation of transcription, DNA-templated. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Located in nucleoplasm. Part of Sin3 complex and transcription repressor complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09594977).

The PHF12 c.2317G>A variant is predicted to result in the amino acid substitution p.Val773Ile. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
