The c.437C>T (p.A146V) alteration is located in exon 5 (coding exon 5) of the TRAPPC3L gene. This alteration results from a C to T substitution at nucleotide position 437, causing the alanine (A) at amino acid position 146 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
