Genes affected
TRAPPC11 (HGNC:25751): (trafficking protein particle complex subunit 11) The protein encoded by this gene is a subunit of the TRAPP (transport protein particle) tethering complex, which functions in intracellular vesicle trafficking. This subunit is involved in early stage endoplasmic reticulum-to-Golgi vesicle transport. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jan 2013]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -17 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 4-183666334-A-C is Benign according to our data. Variant chr4-183666334-A-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 261452.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=-3.67 with no splicing effect.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00067 (102/152232) while in subpopulation NFE AF = 0.00129 (88/68038). AF 95% confidence interval is 0.00107. There are 0 homozygotes in GnomAd4. There are 47 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
