Genes affected

PRMT8 (HGNC:5188): (protein arginine methyltransferase 8) Arginine methylation is a widespread posttranslational modification mediated by arginine methyltransferases, such as PRMT8. Arginine methylation is involved in a number of cellular processes, including DNA repair, RNA transcription, signal transduction, protein compartmentalization, and possibly protein translation (Lee et al., 2005 [PubMed 16051612]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Sep 04, 2024

The c.97C>T (p.P33S) alteration is located in exon 2 (coding exon 2) of the PRMT8 gene. This alteration results from a C to T substitution at nucleotide position 97, causing the proline (P) at amino acid position 33 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
