Although only 11 cases of paternal uniparental disomy 14 (patUPD14) have been reported, a distinct clinically recognizable syndrome has emerged. The major features are polyhydramnios, small thorax, mildly short limbs, abdominal wall defects, and characteristic face with short palpebral fissures, broad flat nasal bridge, prominent philtrum, and small ears. Radiographically, the chest is bell\u2010shaped and the ribs are distinctive with caudal bowing anteriorly and cranial bowing posteriorly. Several affected infants have died from respiratory failure. The survivors have short stature and mental retardation. The initial cases were all recognized because of translocations involving chromosome 14. Subsequently, several patients with a similar phenotype and normal chromosomes have been reported, including two with mixed iso\u2010 and hetero\u2010disomy as well as one with segmental UPD14. Our patient is the first with pure paternal isodisomy 14 in the absence of a translocation. We present additional clinical information, review the literature, and discuss mechanisms that may explain paternal isodisomy 14 in our chromosomally normal patient. Paternal UPD14 with normal karyotype may be more common than previously suspected and may be overlooked unless recognition of the clinical phenotype prompts investigation for UPD. \u00a9 2003
