The c.194C>T (p.T65M) alteration is located in exon 2 (coding exon 1) of the TMEM187 gene. This alteration results from a C to T substitution at nucleotide position 194, causing the threonine (T) at amino acid position 65 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
