The c.1600G>A (p.V534I) alteration is located in exon 10 (coding exon 10) of the GALNT18 gene. This alteration results from a G to A substitution at nucleotide position 1600, causing the valine (V) at amino acid position 534 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
