Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 03, 2024The c.299G>T (p.R100L) alteration is located in exon 4 (coding exon 4) of the TRAPPC6B gene. This alteration results from a G to T substitution at nucleotide position 299, causing the arginine (R) at amino acid position 100 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
