Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.799G>A (p.V267I) alteration is located in exon 5 (coding exon 4) of the CD22 gene. This alteration results from a G to A substitution at nucleotide position 799, causing the valine (V) at amino acid position 267 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
