Ambry Genetics

Nov 07, 2022

The c.330C>A (p.F110L) alteration is located in exon 4 (coding exon 3) of the URB2 gene. This alteration results from a C to A substitution at nucleotide position 330, causing the phenylalanine (F) at amino acid position 110 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
