New familial syndrome of unilateral upper eyelid coloboma, aberrant anterior hairline pattern, and anal anomalies in Manitoba Indians

Am J Med Genet. 1992 Apr 1;42(6):793-9. doi: 10.1002/ajmg.1320420609.


We report on 6 (3 male, 3 female) Manitoba Indian children with hypertelorism and variable combinations of unilateral eye malformations, aberrant anterolateral scalp hairline, and nasal and anal anomalies. These children belong to 4 related families. The parents and 7 other sibs are clinically unaffected. The family histories are otherwise unremarkable. The presence of 2 major malformations in sibs and related individuals (with unaffected parents) suggests that this is a newly described pleiotropic autosomal recessive syndrome. The differential diagnosis includes cryptophthalmos syndrome and several other related malformation syndromes. Although multifactorial determination cannot be excluded, the inbred, isolated population and distribution make autosomal recessive inheritance more likely.
