Genes affected

SLC16A1 (HGNC:10922): (solute carrier family 16 member 1) The protein encoded by this gene is a proton-linked monocarboxylate transporter that catalyzes the movement of many monocarboxylates, such as lactate and pyruvate, across the plasma membrane. Mutations in this gene are associated with erythrocyte lactate transporter defect. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP6: Variant 1-112956232-C-CG is Benign according to our data. Variant chr1-112956232-C-CG is described in ClinVar as [Likely_benign]. Clinvar id is 291916.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.01 (1523/152204) while in subpopulation AFR AF= 0.0339 (1410/41538). AF 95% confidence interval is 0.0325. There are 26 homozygotes in gnomad4. There are 715 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 26 SD gene
