Ambry Genetics

Jul 19, 2023

The c.1025T>C (p.F342S) alteration is located in exon 12 (coding exon 12) of the B3GNTL1 gene. This alteration results from a T to C substitution at nucleotide position 1025, causing the phenylalanine (F) at amino acid position 342 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
