Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.13G>A (p.G5S) alteration is located in exon 2 (coding exon 1) of the CD22 gene. This alteration results from a G to A substitution at nucleotide position 13, causing the glycine (G) at amino acid position 5 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
