The c.637G>A (p.V213I) alteration is located in exon 7 (coding exon 5) of the ADAD1 gene. This alteration results from a G to A substitution at nucleotide position 637, causing the valine (V) at amino acid position 213 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
