Genes affected

KMT5C (HGNC:28405): (lysine methyltransferase 5C) SUV420H2 and the related enzyme SUV420H1 (MIM 610881) function as histone methyltransferases that specifically trimethylate nucleosomal histone H4 (see MIM 602822) on lysine-20 (K20) (Schotta et al., 2004 [PubMed 15145825]).[supplied by OMIM, Dec 2009]

Ambry Genetics

Jun 18, 2021

The c.88C>T (p.R30C) alteration is located in exon 2 (coding exon 1) of the KMT5C gene. This alteration results from a C to T substitution at nucleotide position 88, causing the arginine (R) at amino acid position 30 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
