Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2023The c.445C>T (p.P149S) alteration is located in exon 4 (coding exon 3) of the CD22 gene. This alteration results from a C to T substitution at nucleotide position 445, causing the proline (P) at amino acid position 149 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
