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.823G>A (p.A275T) alteration is located in exon 8 (coding exon 6) of the PRMT2 gene. This alteration results from a G to A substitution at nucleotide position 823, causing the alanine (A) at amino acid position 275 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
