Genes affected
RSRC1 (HGNC:24152): (arginine and serine rich coiled-coil 1) This gene encodes a member of the serine and arginine rich-related protein family. The encoded protein is involved in both constitutive and alternative mRNA splicing. This gene may be associated with schizophrenia. A pseudogene of this gene is located on chromosome 9. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2012]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000134 (18/1346654) while in subpopulation MID AF = 0.00113 (6/5294). AF 95% confidence interval is 0.000493. There are 0 homozygotes in GnomAdExome4. There are 10 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.10C>T (p.R4W) alteration is located in exon 2 (coding exon 1) of the RSRC1 gene. This alteration results from a C to T substitution at nucleotide position 10, causing the arginine (R) at amino acid position 4 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
