Ambry Genetics

Apr 01, 2022

The c.2236C>T (p.P746S) alteration is located in exon 14 (coding exon 13) of the AKNAD1 gene. This alteration results from a C to T substitution at nucleotide position 2236, causing the proline (P) at amino acid position 746 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
