Feb 22, 2023

The c.580T>C (p.C194R) alteration is located in exon 3 (coding exon 3) of the TMEM178B gene. This alteration results from a T to C substitution at nucleotide position 580, causing the cysteine (C) at amino acid position 194 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
