Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 15, 2024The c.74G>A (p.R25Q) alteration is located in exon 1 (coding exon 1) of the TRAPPC4 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
