Genes affected

TRAPPC9 (HGNC:30832): (trafficking protein particle complex subunit 9) This gene encodes a protein that likely plays a role in NF-kappa-B signaling. Mutations in this gene have been associated with autosomal-recessive cognitive disability. Alternatively spliced transcript variants have been described.[provided by RefSeq, Feb 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.02950573).

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000592 (85/1434856) while in subpopulation MID AF = 0.00175 (10/5728). AF 95% confidence interval is 0.000946. There are 1 homozygotes in GnomAdExome4. There are 52 alleles in the male GnomAdExome4 subpopulation. Median coverage is 34. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
