Genes affected

SMARCA5 (HGNC:11101): (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 5) The protein encoded by this gene is a member of the SWI/SNF family of proteins. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. The protein encoded by this gene is a component of the chromatin remodeling and spacing factor RSF, a facilitator of the transcription of class II genes by RNA polymerase II. The encoded protein is similar in sequence to the Drosophila ISWI chromatin remodeling protein. [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, SMARCA5
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.976
• PP5: Variant 4-143528006-A-C is Pathogenic according to our data. Variant chr4-143528006-A-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 599594.Status of the report is no_assertion_criteria_provided, 0 stars.
