Ambry Genetics

Sep 20, 2023

The c.73C>T (p.L25F) alteration is located in exon 2 (coding exon 2) of the RABL3 gene. This alteration results from a C to T substitution at nucleotide position 73, causing the leucine (L) at amino acid position 25 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
