The c.368C>T (p.A123V) alteration is located in exon 1 (coding exon 1) of the TMEM178B gene. This alteration results from a C to T substitution at nucleotide position 368, causing the alanine (A) at amino acid position 123 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
