Apr 07, 2023

The c.1232C>T (p.P411L) alteration is located in exon 15 (coding exon 15) of the SLC38A6 gene. This alteration results from a C to T substitution at nucleotide position 1232, causing the proline (P) at amino acid position 411 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
