The c.551G>A (p.C184Y) alteration is located in exon 5 (coding exon 4) of the SLC16A9 gene. This alteration results from a G to A substitution at nucleotide position 551, causing the cysteine (C) at amino acid position 184 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
