Genes affected

ZMYM3 (HGNC:13054): (zinc finger MYM-type containing 3) This gene is located on the X chromosome and is subject to X inactivation. It is highly conserved in vertebrates and most abundantly expressed in the brain. The encoded protein is a component of histone deacetylase-containing multiprotein complexes that function through modifying chromatin structure to keep genes silent. A chromosomal translocation (X;13) involving this gene is associated with X-linked cognitive disability. Several alternatively spliced transcript variants have been found for this gene.

The c.3740G>A (p.R1247Q) alteration is located in exon 23 (coding exon 22) of the ZMYM3 gene. This alteration results from a G to A substitution at nucleotide position 3740, causing the arginine (R) at amino acid position 1247 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
