Ambry Genetics

Feb 27, 2023

The c.107C>A (p.P36H) alteration is located in exon 1 (coding exon 1) of the NAV2 gene. This alteration results from a C to A substitution at nucleotide position 107, causing the proline (P) at amino acid position 36 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
