Genes affected

SLC2A10 (HGNC:13444): (solute carrier family 2 member 10) This gene encodes a member of the class III facilitative glucose transporter family. The encoded protein plays a role in regulation of glucose homeostasis. Mutations in this gene have been associated with arterial tortuosity syndrome.[provided by RefSeq, Dec 2009]

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 20-46726334-G-A is Benign according to our data. Variant chr20-46726334-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 139175.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00892 (1359/152286) while in subpopulation SAS AF = 0.0154 (74/4816). AF 95% confidence interval is 0.0133. There are 6 homozygotes in GnomAd4. There are 628 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 6 AR gene
