Ambry Genetics

Dec 03, 2024

The c.407A>C (p.K136T) alteration is located in exon 2 (coding exon 2) of the GDE1 gene. This alteration results from a A to C substitution at nucleotide position 407, causing the lysine (K) at amino acid position 136 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
