phenotypes
All alleles(22) : Targeted(8) Gene trapped(9) Spontaneous(3) Chemically induced(2)
 
Homozygous targeted null or spontaneous mutants show circling and head-tossing behavior and are deaf with inner ear dysmorphology. Paternal inheritance of a deletion of an imprinted control region within an intron of this gene results in small body size.
