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 made for transcript

Verdict is Benign. Variant got -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.008291423).
BP6
Variant 8-140451105-T-C is Benign according to our data. Variant chr8-140451105-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 212437.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000591 (9/152246) while in subpopulation SAS AF= 0.00187 (9/4818). AF 95% confidence interval is 0.000974. There are 0 homozygotes in gnomad4. There are 8 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
