Ambry Genetics

Jun 02, 2024

The c.77C>T (p.P26L) alteration is located in exon 1 (coding exon 1) of the DBX2 gene. This alteration results from a C to T substitution at nucleotide position 77, causing the proline (P) at amino acid position 26 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
