Genes affected
MEF2D (HGNC:6997): (myocyte enhancer factor 2D) This gene is a member of the myocyte-specific enhancer factor 2 (MEF2) family of transcription factors. Members of this family are involved in control of muscle and neuronal cell differentiation and development, and are regulated by class II histone deacetylases. Fusions of the encoded protein with Deleted in Azoospermia-Associated Protein 1 (DAZAP1) due to a translocation have been found in an acute lymphoblastic leukemia cell line, suggesting a role in leukemogenesis. The encoded protein may also be involved in Parkinson disease and myotonic dystrophy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2012]

The c.1460G>A (p.R487Q) alteration is located in exon 11 (coding exon 10) of the MEF2D gene. This alteration results from a G to A substitution at nucleotide position 1460, causing the arginine (R) at amino acid position 487 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
