Ambry Genetics

Feb 22, 2023

The c.3080C>T (p.P1027L) alteration is located in exon 25 (coding exon 25) of the OVCH1 gene. This alteration results from a C to T substitution at nucleotide position 3080, causing the proline (P) at amino acid position 1027 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
