Genes affected

SLC26A7 (HGNC:14467): (solute carrier family 26 member 7) This gene is one member of a family of sulfate/anion transporter genes. Family members are well conserved in gene structure and protein length yet have markedly different tissue expression patterns. This gene has abundant and specific expression in the kidney. Alternatively spliced transcript variants that encode different isoforms have been described. [provided by RefSeq, Aug 2013]

The c.62G>A (p.C21Y) alteration is located in exon 2 (coding exon 1) of the SLC26A7 gene. This alteration results from a G to A substitution at nucleotide position 62, causing the cysteine (C) at amino acid position 21 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
