Genes affected

HDAC7 (HGNC:14067): (histone deacetylase 7) 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 has sequence homology to members of the histone deacetylase family. This gene is orthologous to mouse HDAC7 gene whose protein promotes repression mediated via the transcriptional corepressor SMRT. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The c.2420C>G (p.P807R) alteration is located in exon 21 (coding exon 21) of the HDAC7 gene. This alteration results from a C to G substitution at nucleotide position 2420, causing the proline (P) at amino acid position 807 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
