The c.1418C>T (p.A473V) alteration is located in exon 12 (coding exon 11) of the ASUN gene. This alteration results from a C to T substitution at nucleotide position 1418, causing the alanine (A) at amino acid position 473 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
