Genes affected

SMYD3 (HGNC:15513): (SET and MYND domain containing 3) This gene encodes a histone methyltransferase which functions in RNA polymerase II complexes by an interaction with a specific RNA helicase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

The c.772T>G (p.C258G) alteration is located in exon 8 (coding exon 8) of the SMYD3 gene. This alteration results from a T to G substitution at nucleotide position 772, causing the cysteine (C) at amino acid position 258 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
