Microphthalmia, facial anomalies, microcephaly, thumb and hallux hypoplasia, and agammaglobulinemia.

We report a boy, born to consanguineous patients, with agammaglobulinemia associated with multiple physical anomalies: mild intrauterine growth retardation, extreme microphthalmia (clinical anophthalmia), severe microcephaly, blepharophimosis, long face with temporal narrowing, scaphocephalic skull shape, posterior cleft palate, hypoplastic, adducted thumbs with small nails, and short, inward turned halluces with absent distal phalanges and nails. Psychomotor development was moderately delayed. No mutations were found in exons of BKT and PAX-5 genes. This unreported constellation could represent a novel, autosomal recessive syndrome.
