Genes affected

BRPF1 (HGNC:14255): (bromodomain and PHD finger containing 1) This gene encodes a bromodomain, PHD finger and chromo/Tudor-related Pro-Trp-Trp-Pro (PWWP) domain containing protein. The encoded protein is a component of the MOZ/MORF histone acetyltransferase complexes which function as a transcriptional regulators. This protein binds to the catalytic MYST domains of the MOZ and MORF proteins and may play a role in stimulating acetyltransferase and transcriptional activity of the complex. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

BRPF1 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), BRPF1. . Gene score misZ 3.8305 (greater than the threshold 3.09). Trascript score misZ 4.9876 (greater than threshold 3.09). GenCC has associacion of gene with intellectual developmental disorder with dysmorphic facies and ptosis.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.883
• PP5: Variant 3-9739352-G-A is Pathogenic according to our data. Variant chr3-9739352-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 445981.Status of the report is criteria_provided_single_submitter, 1 stars.
