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)

This sequence change creates a premature translational stop signal (p.Arg313*) in the SLC16A1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC16A1 are known to be pathogenic (PMID: 25390740). This variant is present in population databases (rs606231299, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with autosomal recessive SLC16A1-related conditions (PMID: 25390740). ClinVar contains an entry for this variant (Variation ID: 158079). For these reasons, this variant has been classified as Pathogenic.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Stop-gained (nonsense) is predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 25390740). The variant has been reported to be associated with SLC16A1-related disorder (ClinVar ID: VCV000158079 / PMID: 25390740). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline.
