FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the immunoglobulin superfamily of cell adhesion molecules (Ig-CAMs), and is involved in human central and peripheral nervous system development. This gene is a candidate for Down syndrome and congenital heart disease (DSCHD). A gene encoding a similar Ig-CAM protein is located on chromosome 11. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2012]
PHENOTYPE: Mice homozygous for a null allele exhibit background-sensitive perinatal lethality associated with respiratory distress, altered C4 ventral root and pre-inspiratory neuron signaling, and abnormal response to hypercapnia. [provided by MGI curators]
