Variant 16-2763176-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_016333.4(SRRM2):c.2648C>T(p.Ser883Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,613,950 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S883C) has been classified as Likely benign.

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.
