The c.206C>T (p.S69L) alteration is located in exon 3 (coding exon 2) of the CD22 gene. This alteration results from a C to T substitution at nucleotide position 206, causing the serine (S) at amino acid position 69 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
