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.

Jan 10, 2023

The c.401G>A (p.R134Q) alteration is located in exon 6 (coding exon 5) of the HDAC6 gene. This alteration results from a G to A substitution at nucleotide position 401, causing the arginine (R) at amino acid position 134 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
