The c.869A>G (p.Y290C) alteration is located in exon 5 (coding exon 4) of the SLC16A9 gene. This alteration results from a A to G substitution at nucleotide position 869, causing the tyrosine (Y) at amino acid position 290 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
