The c.850G>A (p.V284I) alteration is located in exon 9 (coding exon 8) of the SLC28A2 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the valine (V) at amino acid position 284 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
