Genes affected
AP4S1 (HGNC:575): (adaptor related protein complex 4 subunit sigma 1) This gene encodes a member of the adaptor complexes small 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 the small subunit of adaptor protein complex-4, which is associated with both clathrin- and nonclathrin-coated vesicles. Mutations in this gene are associated with spastic quadriplegic cerebral palsy-6. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.18).
BP6
Variant 14-31066320-C-A is Benign according to our data. Variant chr14-31066320-C-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 128406.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000302 (46/152282) while in subpopulation SAS AF= 0.00912 (44/4824). AF 95% confidence interval is 0.00698. There are 0 homozygotes in gnomad4. There are 34 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 7 AR gene
