Genes affected

SLC5A1 (HGNC:11036): (solute carrier family 5 member 1) This gene encodes a member of the sodium-dependent glucose transporter (SGLT) family. The encoded integral membrane protein is the primary mediator of dietary glucose and galactose uptake from the intestinal lumen. Mutations in this gene have been associated with glucose-galactose malabsorption. Multiple transcript variants encoding different isoforms have been found for this gene.

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 nfe. GnomAd4 allele frequency = 0.00134 (204/152344) while in subpopulation NFE AF = 0.00271 (184/68020). AF 95% confidence interval is 0.00239. There are 0 homozygotes in GnomAd4. There are 99 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
