A syndrome that combines agammaglobulinemia with marked microcephaly, significant developmental delay, craniosynostosis, a severe dermatitis, cleft palate, narrowing of the choanae, and blepharophimosis. It has been described in three siblings, two males and one female, born to nonconsanguineous parents. Transmission is probably autosomal recessive. It has been suggested that this syndrome represents a new form of agammaglobulinemia due to a defect in early B-cell maturation.

Cleft palate is a developmental defect of the palate resulting from a failure of fusion of the palatine processes and manifesting as a separation of the roof of the mouth (soft and hard palate).
