Ambry Genetics

Apr 15, 2024

The c.645A>C (p.K215N) alteration is located in exon 4 (coding exon 4) of the TMEM225 gene. This alteration results from a A to C substitution at nucleotide position 645, causing the lysine (K) at amino acid position 215 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
