Genes affected
KMT2C (HGNC:13726): (lysine methyltransferase 2C) This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a RING-type zinc finger. This protein is a member of the ASC-2/NCOA6 complex (ASCOM), which possesses histone methylation activity and is involved in transcriptional coactivation. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.4592C>T (p.A1531V) alteration is located in exon 31 (coding exon 31) of the KMT2C gene. This alteration results from a C to T substitution at nucleotide position 4592, causing the alanine (A) at amino acid position 1531 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
