Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.271A>G (p.I91V) alteration is located in exon 4 (coding exon 4) of the TRAPPC6B gene. This alteration results from a A to G substitution at nucleotide position 271, causing the isoleucine (I) at amino acid position 91 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
