Genes affected

HDAC10 (HGNC:18128): (histone deacetylase 10) The protein encoded by this gene belongs to the histone deacetylase family, members of which deacetylate lysine residues on the N-terminal part of the core histones. Histone deacetylation modulates chromatin structure, and plays an important role in transcriptional regulation, cell cycle progression, and developmental events. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

HDAC10 links:

MAPK12 (HGNC:6874): (mitogen-activated protein kinase 12) Activation of members of the mitogen-activated protein kinase family is a major mechanism for transduction of extracellular signals. Stress-activated protein kinases are one subclass of MAP kinases. The protein encoded by this gene functions as a signal transducer during differentiation of myoblasts to myotubes.

The c.1384A>G (p.K462E) alteration is located in exon 14 (coding exon 14) of the HDAC10 gene. This alteration results from a A to G substitution at nucleotide position 1384, causing the lysine (K) at amino acid position 462 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
