Genes affected
AP4E1 (HGNC:573): (adaptor related protein complex 4 subunit epsilon 1) This gene encodes a member of the adaptor complexes large subunit protein family. These proteins are components of the heterotetrameric adaptor protein complexes, which play important roles in the secretory and endocytic pathways by mediating vesicle formation and sorting of integral membrane proteins. The encoded protein is a large subunit of adaptor protein complex-4, which is associated with both clathrin- and nonclathrin-coated vesicles. Disruption of this gene may be associated with cerebral palsy. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.005823791).
BP6
Variant 15-50999099-C-T is Benign according to our data. Variant chr15-50999099-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 434236.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000335 (51/152204) while in subpopulation SAS AF = 0.00416 (20/4812). AF 95% confidence interval is 0.00275. There are 0 homozygotes in GnomAd4. There are 28 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 3 AR gene
