Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2022The c.613A>C (p.K205Q) alteration is located in exon 4 (coding exon 3) of the CD22 gene. This alteration results from a A to C substitution at nucleotide position 613, causing the lysine (K) at amino acid position 205 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
