Mohr syndrome (oro-facial-digital syndrome II)--a familial case with different phenotypic findings.
We report on two male siblings with an oro-facial-digital syndrome. The parents and two other siblings, a boy and a girl, are unaffected. The clinical findings on the reported brothers were different. Patient 1 had typical oral, facial and digital anomalies plus hypoplastic genitalia and short limbs. Clinically he had marked hypotonia, convulsions and apneic episodes. He died shortly after birth. His brother, Patient 2, had OFD features with conductive hearing loss and normal psychomental development. He did not have syndactylous reduplication of the great toes, although the toes were disproportionately large. These two patients are classified as OFD type II-Mohr syndrome. Involvement of the central nervous system in OFD type II is noted. Different phenotypic findings could be explained as variable gene expressivity. The patients described here support the hypothesis that the clinical variability of the Mohr syndrome is even wider than previously thought.
