Genes affected

SLCO1C1 (HGNC:13819): (solute carrier organic anion transporter family member 1C1) This gene encodes a member of the organic anion transporter family. The encoded protein is a transmembrane receptor that mediates the sodium-independent uptake of thyroid hormones in brain tissues. This protein has particularly high affinity for the thyroid hormones thyroxine, tri-iodothyronine and reverse tri-iodothyronine. Polymorphisms in the gene encoding this protein may be associated with fatigue and depression in patients suffering from hyperthyroidism. Alternative splicing results in multiple transcript variants.

The c.759T>G (p.I253M) alteration is located in exon 8 (coding exon 6) of the SLCO1C1 gene. This alteration results from a T to G substitution at nucleotide position 759, causing the isoleucine (I) at amino acid position 253 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
