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]

This sequence change creates a premature translational stop signal (p.Tyr26Serfs*21) in the PRMT7 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in PRMT7 are known to be pathogenic (PMID: 26437029, 27718516). This variant has not been reported in the literature in individuals with PRMT7-related conditions. This variant is not present in population databases (ExAC no frequency). -
