Genes affected

PRMT2 (HGNC:5186): (protein arginine methyltransferase 2) Enables several functions, including nuclear receptor binding activity; peroxisome proliferator activated receptor binding activity; and protein homodimerization activity. Involved in several processes, including histone methylation; regulation of androgen receptor signaling pathway; and regulation of transcription, DNA-templated. Located in cytosol and nucleoplasm.

The c.239C>T (p.P80L) alteration is located in exon 5 (coding exon 3) of the PRMT2 gene. This alteration results from a C to T substitution at nucleotide position 239, causing the proline (P) at amino acid position 80 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
