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]

Ambry Genetics

Nov 08, 2022

The c.572A>G (p.Q191R) alteration is located in exon 6 (coding exon 6) of the SMYD3 gene. This alteration results from a A to G substitution at nucleotide position 572, causing the glutamine (Q) at amino acid position 191 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
