Ambry Genetics

Apr 13, 2022

The c.1171T>C (p.F391L) alteration is located in exon 12 (coding exon 12) of the GADL1 gene. This alteration results from a T to C substitution at nucleotide position 1171, causing the phenylalanine (F) at amino acid position 391 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
