Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2
The NM_001160372.4(TRAPPC9):c.3149G>A(p.Arg1050Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00187 in 1,606,834 control chromosomes in the GnomAD database, including 9 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1050W) has been classified as Likely benign.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 09, 2018 | The p.R1148Q variant (also known as c.3443G>A), located in coding exon 22 of the TRAPPC9 gene, results from a G to A substitution at nucleotide position 3443. The arginine at codon 1148 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
