Ambry Genetics

Sep 14, 2022

The c.296A>G (p.Y99C) alteration is located in exon 4 (coding exon 3) of the TMEM71 gene. This alteration results from a A to G substitution at nucleotide position 296, causing the tyrosine (Y) at amino acid position 99 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
