Collection Method: clinical testing

The c.1720C>T (p.P574S) alteration is located in exon 16 (coding exon 14) of the SLC5A6 gene. This alteration results from a C to T substitution at nucleotide position 1720, causing the proline (P) at amino acid position 574 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
