Collection Method: clinical testing

The c.671G>C (p.C224S) alteration is located in exon 7 (coding exon 6) of the SLC17A2 gene. This alteration results from a G to C substitution at nucleotide position 671, causing the cysteine (C) at amino acid position 224 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
