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]

SLC16A1-AS1 (HGNC:49445): (SLC16A1 antisense RNA 1)

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-112917820-G-A is Pathogenic according to our data. Variant chr1-112917820-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 158081.Status of the report is no_assertion_criteria_provided, 0 stars.
