Ambry Genetics

Apr 28, 2023

The c.2492C>T (p.P831L) alteration is located in exon 12 (coding exon 12) of the ABTB2 gene. This alteration results from a C to T substitution at nucleotide position 2492, causing the proline (P) at amino acid position 831 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
