The c.400A>G (p.M134V) alteration is located in exon 1 (coding exon 1) of the SNX29 gene. This alteration results from a A to G substitution at nucleotide position 400, causing the methionine (M) at amino acid position 134 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
