Ambry Genetics

Apr 14, 2022

The c.242G>C (p.R81P) alteration is located in exon 1 (coding exon 1) of the TMEM178B gene. This alteration results from a G to C substitution at nucleotide position 242, causing the arginine (R) at amino acid position 81 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
