Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2024The c.539A>G (p.K180R) alteration is located in exon 5 (coding exon 5) of the TRAPPC3L gene. This alteration results from a A to G substitution at nucleotide position 539, causing the lysine (K) at amino acid position 180 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
