Genes affected

SLC5A2 (HGNC:11037): (solute carrier family 5 member 2) This gene encodes a member of the sodium glucose cotransporter family which are sodium-dependent glucose transport proteins. The encoded protein is the major cotransporter involved in glucose reabsorption in the kidney. Mutations in this gene are associated with renal glucosuria. Two transcript variants, one protein-coding and one not, have been found for this gene. [provided by RefSeq, Feb 2015]

The c.86T>C (p.I29T) alteration is located in exon 1 (coding exon 1) of the SLC5A2 gene. This alteration results from a T to C substitution at nucleotide position 86, causing the isoleucine (I) at amino acid position 29 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
