The c.433G>A (p.G145R) alteration is located in exon 2 (coding exon 1) of the TMEM119 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the glycine (G) at amino acid position 145 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
