Collection Method:clinical testing

The c.682C>A (p.L228I) alteration is located in exon 5 (coding exon 4) of the SLC16A9 gene. This alteration results from a C to A substitution at nucleotide position 682, causing the leucine (L) at amino acid position 228 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
