MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a homeodomain-containing transcription factor. The encoded protein is a member of the NKX family of homeodomain transcription factors. Studies of similar proteins in mouse and rat have indicated a potential role in cellular differentiation.[provided by RefSeq, Mar 2010]
PHENOTYPE: Homozygotes exhibit postnatal lethality due to acute intestinal malabsorption. Survivors recover well but exhibit splenic and Peyer's patch hypoplasia, intestinal villus malformation, gut truncation and distension, abnormal molar and sublingual gland development, and deranged lymphocyte homing.
