Collection Method: clinical testing

The c.362C>T (p.P121L) alteration is located in exon 4 (coding exon 3) of the SLC16A4 gene. This alteration results from a C to T substitution at nucleotide position 362, causing the proline (P) at amino acid position 121 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
