Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBS1_Supporting

The NM_001271838.2(RSRC1):c.172C>T(p.Arg58Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000531 in 1,582,194 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R58H) has been classified as Uncertain significance.

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 -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.15240386).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000151 (23/152214) while in subpopulation AFR AF = 0.000361 (15/41558). AF 95% confidence interval is 0.000222. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. 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.172C>T (p.R58C) 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 172, causing the arginine (R) at amino acid position 58 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
