Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.7A>G (p.I3V) alteration is located in exon 1 (coding exon 1) of the TRAPPC4 gene. This alteration results from a A to G substitution at nucleotide position 7, causing the isoleucine (I) at amino acid position 3 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
