Collection Method: clinical testing

The c.613C>A (p.P205T) alteration is located in exon 9 (coding exon 9) of the TRAPPC13 gene. This alteration results from a C to A substitution at nucleotide position 613, causing the proline (P) at amino acid position 205 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
