Variant summary

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

The NM_004963.4(GUCY2C):​c.3146G>A​(p.Arg1049Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000018 in 1,613,400 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict 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. R1049W) has been classified as Uncertain significance.

Genes affected
GUCY2C (HGNC:4688): (guanylate cyclase 2C) This gene encodes a transmembrane protein that functions as a receptor for endogenous peptides guanylin and uroguanylin, and the heat-stable E. coli enterotoxin. The encoded protein activates the cystic fibrosis transmembrane conductance regulator. Mutations in this gene are associated with familial diarrhea (autosomal dominant) and meconium ileus (autosomal recessive). [provided by RefSeq, Nov 2016]
PLBD1-AS1 (HGNC:51143): (PLBD1 antisense RNA 1)

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=0.07942301).
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000263 (4/152172) while in subpopulation SAS AF = 0.000622 (3/4826). AF 95% confidence interval is 0.000169. There are 1 homozygotes in GnomAd4. There are 2 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
