The c.418G>T (p.G140C) alteration is located in exon 2 (coding exon 2) of the ARRDC5 gene. This alteration results from a G to T substitution at nucleotide position 418, causing the glycine (G) at amino acid position 140 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
