Collection Method:clinical testing

The c.614C>T (p.T205I) alteration is located in exon 3 (coding exon 3) of the WBSCR28 gene. This alteration results from a C to T substitution at nucleotide position 614, causing the threonine (T) at amino acid position 205 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
