Function
Part of the WAVE complex that regulates lamellipodia formation. The WAVE complex regulates actin filament reorganization via its interaction with the Arp2/3 complex. Actin remodeling activity is regulated by RAC1. As component of the WAVE1 complex, required for BDNF-NTRK2 endocytic trafficking and signaling from early endosomes. {ECO:0000250|UniProtKB:P28660}.

HI Disease:
  • Complex Neurodevelopmental Disorder Monarch
HI Evidence:
  • PUBMED: 27632392
    Freed and Pevsner (2016) reported a de novo (potentially mosaic) frameshift variant (NM_205842.2:c.524_525insGT/p.Ala176X) in a patient with autism spectrum disorder.
  • PUBMED: 27824329
    Wang et al., (2016) detected a de novo splicing variant c.3180+ 1G>A in a Chinese patient with ASD and global developmental delay among 1,543 probands with ASD.
  • PUBMED: 28940097
    Anazi et al. (2017) reported a heterozygous nonsense variant c.3298G>T:p.Glu1100* segregated with intellectual disability in a large multigenerational family in an effort for discovering novel genetic causes of intellectual disability. This four generation pedigree had a total of 13 affected (not all were genotyped). Seven heterzygous carriers that were genotyped were all affected. Two unaffected individuals had normal genotype. The gene expression pattern suppport the involvement of NCKAP1 in brain function.
HI Evidence Comments:
This gene is extremely constrained against haploinsufficency in the human genome. Currently at least three independent null variants had been reported in patients with developmental delay (DD), autism spectrum disorder (ASD) and/or intellectual disability (ID). Multiple patients with large deletion involving this gene (and many other genes) exhibited DD/ID/ASD. No deletion involving NCKAP1 was reported in normal populations.
