The c.638G>T (p.G213V) alteration is located in exon 6 (coding exon 5) of the ASUN gene. This alteration results from a G to T substitution at nucleotide position 638, causing the glycine (G) at amino acid position 213 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
