Ambry Genetics

Dec 01, 2022

The c.833A>G (p.Y278C) alteration is located in exon 9 (coding exon 8) of the BABAM1 gene. This alteration results from a A to G substitution at nucleotide position 833, causing the tyrosine (Y) at amino acid position 278 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
