Collection Method: clinical testing

The c.67C>T (p.P23S) alteration is located in exon 2 (coding exon 2) of the SLC31A2 gene. This alteration results from a C to T substitution at nucleotide position 67, causing the proline (P) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
