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]

The c.983C>A (p.P328H) alteration is located in exon 9 (coding exon 8) of the KMT5C gene. This alteration results from a C to A substitution at nucleotide position 983, causing the proline (P) at amino acid position 328 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
