Ambry Genetics

Nov 09, 2023

The c.2203G>C (p.A735P) alteration is located in exon 5 (coding exon 5) of the CHADL gene. This alteration results from a G to C substitution at nucleotide position 2203, causing the alanine (A) at amino acid position 735 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
