Ambry Genetics

Nov 29, 2021

The c.289G>T (p.D97Y) alteration is located in exon 3 (coding exon 2) of the CD22 gene. This alteration results from a G to T substitution at nucleotide position 289, causing the aspartic acid (D) at amino acid position 97 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
