Genes affected

IQSEC1 (HGNC:29112): (IQ motif and Sec7 domain ArfGEF 1) Predicted to enable protein kinase binding activity. Predicted to be involved in several processes, including positive regulation of focal adhesion disassembly; positive regulation of keratinocyte migration; and regulation of postsynaptic neurotransmitter receptor internalization. Located in nucleolus. Implicated in intellectual developmental disorder with short stature and behavioral abnormalities. [provided by Alliance of Genome Resources, Apr 2022]
