The c.49T>G (p.C17G) alteration is located in exon 2 (coding exon 1) of the TMEM175 gene. This alteration results from a T to G substitution at nucleotide position 49, causing the cysteine (C) at amino acid position 17 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
