Collection Method: clinical testing

The c.662C>T (p.S221L) alteration is located in exon 5 (coding exon 4) of the SPDYE2B gene. This alteration results from a C to T substitution at nucleotide position 662, causing the serine (S) at amino acid position 221 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
