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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2023The c.709A>T (p.I237F) alteration is located in exon 8 (coding exon 8) of the SMYD3 gene. This alteration results from a A to T substitution at nucleotide position 709, causing the isoleucine (I) at amino acid position 237 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
