The c.389G>A (p.R130H) alteration is located in exon 1 (coding exon 1) of the SNX29 gene. This alteration results from a G to A substitution at nucleotide position 389, causing the arginine (R) at amino acid position 130 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
