Ambry Genetics

Feb 13, 2023

The c.2081C>T (p.P694L) alteration is located in exon 13 (coding exon 12) of the USHBP1 gene. This alteration results from a C to T substitution at nucleotide position 2081, causing the proline (P) at amino acid position 694 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
