Ambry Genetics

Jun 10, 2024

The c.80G>A (p.C27Y) alteration is located in exon 1 (coding exon 1) of the TMEM178B gene. This alteration results from a G to A substitution at nucleotide position 80, causing the cysteine (C) at amino acid position 27 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
