The c.179G>C (p.G60A) alteration is located in exon 3 (coding exon 3) of the TMEM52B gene. This alteration results from a G to C substitution at nucleotide position 179, causing the glycine (G) at amino acid position 60 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
