A brother and a sister show very similar clinical features, including sparse hair in the first year of life, prominent nose, small mouth, micrognathia, high arched palate or cleft palate, crumpled upper helices, flexion limitation of the distal interphalangeal joint of the fingers, and mild developmental delay. Their clinical appearance suggests a premature aging phenotype, but is not really compatible with the hitherto known syndromes of that group. The mode of inheritance is likely autosomal recessive.
