Head blebs: a new mutation on chromosome 4 of the mouse

Abstract

The development effects and inheritance of a new mutation in the mouse, head blebs, gene symbol heb, are described. This mutation is similar to two other autosomal recessive mutations, eb and my. Head blebs produces abnormal or missing eyes due to prenatal blebs, usually on the head, some fetal death, open eyelids, and folded retinas at birth. Extra toes or ectopic brains are occasionally observed. Affected adults usually have closed eyelids and atrophic eyes. Head blebs is located on chromosome 4, four units from pintail (Pt).
