Ambry Genetics

Sep 01, 2021

The c.1471G>T (p.V491L) alteration is located in exon 11 (coding exon 11) of the RABEP2 gene. This alteration results from a G to T substitution at nucleotide position 1471, causing the valine (V) at amino acid position 491 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
