Ambry Genetics

Dec 20, 2023

The c.394A>G (p.I132V) alteration is located in exon 4 (coding exon 4) of the TMEM39B gene. This alteration results from a A to G substitution at nucleotide position 394, causing the isoleucine (I) at amino acid position 132 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
