Collection Method: clinical testing

The c.419T>C (p.I140T) alteration is located in exon 4 (coding exon 4) of the SPDYE4 gene. This alteration results from a T to C substitution at nucleotide position 419, causing the isoleucine (I) at amino acid position 140 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
