Collection Method: clinical testing

The c.365C>A (p.A122E) alteration is located in exon 4 (coding exon 3) of the SIGLECL1 gene. This alteration results from a C to A substitution at nucleotide position 365, causing the alanine (A) at amino acid position 122 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
