Genetic Variant SRSF12:p.Arg160Pro (chr6-89098885-C-G) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_080743.5(SRSF12):c.479G>C(p.Arg160Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,646 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 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. R160Q) has been classified as Uncertain significance.

Genes affected

SRSF12 (HGNC:21220): (serine and arginine rich splicing factor 12) Enables RNA binding activity. Involved in mRNA 5'-splice site recognition and regulation of alternative mRNA splicing, via spliceosome. Predicted to be located in nucleoplasm. Predicted to be active in cytoplasm and nuclear speck. [provided by Alliance of Genome Resources, Apr 2022]

SRSF12 links:

PM20D2 (HGNC:21408): (peptidase M20 domain containing 2) Enables dipeptidase activity and identical protein binding activity. Acts upstream of or within proteolysis and regulation of cellular protein metabolic process. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
