Genes affected

RSPRY1 (HGNC:29420): (ring finger and SPRY domain containing 1) This gene encodes a glycoprotein that contains a RING-type zinc finger domain and an SPRY domain of unknown function. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.14602849).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000223 (34/152270) while in subpopulation AMR AF= 0.00118 (18/15288). AF 95% confidence interval is 0.000761. There are 0 homozygotes in gnomad4. There are 21 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

The c.140G>A (p.R47Q) alteration is located in exon 2 (coding exon 1) of the RSPRY1 gene. This alteration results from a G to A substitution at nucleotide position 140, causing the arginine (R) at amino acid position 47 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 47 of the RSPRY1 protein (p.Arg47Gln). This variant is present in population databases (rs200607629, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with RSPRY1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1440892). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RSPRY1 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
