Genes affected

PRMT7 (HGNC:25557): (protein arginine methyltransferase 7) This gene encodes a member of the protein arginine N-methyltransferase family of proteins. The encoded enzyme transfers single methyl groups to arginine residues to generate monomethylarginines on histone proteins as well as other protein substrates. This enzyme plays a role in a wide range of biological processes, including neuronal differentiation, male germ line imprinting, small nuclear ribonucleoprotein biogenesis, and regulation of the Wnt signaling pathway. Mutations in this gene underlie multiple related syndromes in human patients characterized by intellectual disability, short stature and other features. The encoded protein may promote breast cancer cell invasion and metastasis in human patients. [provided by RefSeq, May 2017]

Ambry Genetics

Feb 10, 2023

The c.262G>A (p.D88N) alteration is located in exon 5 (coding exon 3) of the PRMT7 gene. This alteration results from a G to A substitution at nucleotide position 262, causing the aspartic acid (D) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
