Genes affected

CARM1 (HGNC:23393): (coactivator associated arginine methyltransferase 1) This gene belongs to the protein arginine methyltransferase (PRMT) family. The encoded enzyme catalyzes the methylation of guanidino nitrogens of arginyl residues of proteins. The enzyme acts specifically on histones and other chromatin-associated proteins and is involved in regulation of gene expression. The enzyme may act in association with other proteins or within multi-protein complexes and may play a role in cell type-specific functions and cell lineage specification. A related pseudogene is located on chromosome 9. [provided by RefSeq, Aug 2013]

The c.164C>A (p.A55E) alteration is located in exon 1 (coding exon 1) of the CARM1 gene. This alteration results from a C to A substitution at nucleotide position 164, causing the alanine (A) at amino acid position 55 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
