Ambry Genetics

May 29, 2024

The c.44G>C (p.G15A) alteration is located in exon 2 (coding exon 1) of the TMEM239 gene. This alteration results from a G to C substitution at nucleotide position 44, causing the glycine (G) at amino acid position 15 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
