Genes affected

SRRM2 (HGNC:16639): (serine/arginine repetitive matrix 2) Enables C2H2 zinc finger domain binding activity and protein N-terminus binding activity. Involved in mRNA splicing, via spliceosome. Located in Cajal body and nuclear speck. Part of U2-type catalytic step 2 spliceosome and U2-type precatalytic spliceosome. Biomarker of Parkinson's disease.

The c.196G>A (p.V66I) alteration is located in exon 2 (coding exon 1) of the SRRM2 gene. This alteration results from a G to A substitution at nucleotide position 196, causing the valine (V) at amino acid position 66 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
