Genes affected

HDAC6 (HGNC:14064): (histone deacetylase 6) Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA. The protein encoded by this gene belongs to class II of the histone deacetylase/acuc/apha family. It contains an internal duplication of two catalytic domains which appear to function independently of each other. This protein possesses histone deacetylase activity and represses transcription.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-48824894-A-T is Pathogenic according to our data. Variant chrX-48824894-A-T is described in ClinVar as [Pathogenic]. Clinvar id is 65387.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).. Strength limited to SUPPORTING due to the PP5.
