Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.302T>G (p.L101R) alteration is located in exon 4 (coding exon 4) of the TRAPPC6B gene. This alteration results from a T to G substitution at nucleotide position 302, causing the leucine (L) at amino acid position 101 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
