Genes affected
NECAP1 (HGNC:24539): (NECAP endocytosis associated 1) This gene encodes a protein containing two characteristic WXXF motifs. The encoded protein localizes to clathrin-coated vesicles, where it binds components of the adapter protein complexes and aids in endocytosis. Loss of function of this gene results in early infantile epileptic encephalopathy-21. There is a pseudogene for this gene on chromosome 7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

BP6
Variant 12-8082357-G-A is Benign according to our data. Variant chr12-8082357-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 783103.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BP7
Synonymous conserved (PhyloP=0.005 with no splicing effect.
BS1
Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.000534 (780/1461356) while in subpopulation EAS AF= 0.017 (674/39682). AF 95% confidence interval is 0.0159. There are 11 homozygotes in gnomad4_exome. There are 397 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 11 AR gene
