Genes affected

KAT5 (HGNC:5275): (lysine acetyltransferase 5) The protein encoded by this gene belongs to the MYST family of histone acetyl transferases (HATs) and was originally isolated as an HIV-1 TAT-interactive protein. HATs play important roles in regulating chromatin remodeling, transcription and other nuclear processes by acetylating histone and nonhistone proteins. This protein is a histone acetylase that has a role in DNA repair and apoptosis and is thought to play an important role in signal transduction. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

RNASEH2C (HGNC:24116): (ribonuclease H2 subunit C) This gene encodes a ribonuclease H subunit that can cleave ribonucleotides from RNA:DNA duplexes. Mutations in this gene cause Aicardi-Goutieres syndrome-3, a disease that causes severe neurologic dysfunction. A pseudogene for this gene has been identified on chromosome Y, near the sex determining region Y (SRY) gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, KAT5
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.982
• PP5: Variant 11-65716922-T-A is Pathogenic according to our data. Variant chr11-65716922-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 987965.Status of the report is no_assertion_criteria_provided, 0 stars.
