The c.654G>C (p.M218I) alteration is located in exon 2 (coding exon 2) of the TMEM132C gene. This alteration results from a G to C substitution at nucleotide position 654, causing the methionine (M) at amino acid position 218 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
