Genes affected

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

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 Gene-Disease associations (from GenCC):

• ketoacidosis due to monocarboxylate transporter-1 deficiency
