Homozygotes for a reporter allele show pre- and postnatal death, head-shaking, and small eyes. Spontaneous mutants show head-shaking, circling, reduced or absent semicircular canals, small abnormal eyes, aberrant cell-cycling, female sterility, and low prenetrance craniofacial and skeletal defects.
