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.

Ambry Genetics

Mar 20, 2024

The c.215G>A (p.R72H) alteration is located in exon 5 (coding exon 3) of the PRMT2 gene. This alteration results from a G to A substitution at nucleotide position 215, causing the arginine (R) at amino acid position 72 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
