Genes affected

GOSR2 (HGNC:4431): (golgi SNAP receptor complex member 2) This gene encodes a trafficking membrane protein which transports proteins among the medial- and trans-Golgi compartments. Due to its chromosomal location and trafficking function, this gene may be involved in familial essential hypertension. [provided by RefSeq, Mar 2016]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.010817587).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000992 (151/152248) while in subpopulation AFR AF= 0.00361 (150/41544). AF 95% confidence interval is 0.00314. There are 0 homozygotes in gnomad4. There are 73 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The p.T108P variant (also known as c.322A>C), located in coding exon 4 of the GOSR2 gene, results from an A to C substitution at nucleotide position 322. The threonine at codon 108 is replaced by proline, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
