Collection Method: clinical testing

The c.53C>T (p.T18I) alteration is located in exon 1 (coding exon 1) of the SPDYE3 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the threonine (T) at amino acid position 18 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
