Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 02, 2024The c.301C>T (p.P101S) alteration is located in exon 2 (coding exon 2) of the TRAPPC4 gene. This alteration results from a C to T substitution at nucleotide position 301, causing the proline (P) at amino acid position 101 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
