| Remarks |
Affected; mother had gestational diabetes which was well controlled; subject required intubation from birth until day of life 4; supplemental feeding by NG tube; mild micrognathia; anteverted tip of the nose; high-arched palate; short and broad neck; low anterior and posterior hairline; generalized mild hypotonia; short stature; bilateral astigmatism; strabismus; early onset morbid obesity, primarily abdominal fat distribution; mildly hypoplastic labia minora; tapered fingers; short 4th and 5th metacarpals; mild scoliosis; obstructive sleep apnea; staring episodes, but no seizures; microsatellite testing revealed maternal uniparental disomy of chromosome 15; normal head ultrasound; normal echo; borderline prolonged QT segment on EKG; head MRI showed delayed myelination pattern; swallow study revealed silent aspiration in supine position only; development assessment using Bayley Scale of Infant Development at approximately 12 months revealed cognitive score:65 (low), language (74) borderline, motor (61) low, social-emotional (60) low, general adaptive (53), low; treatments include occupational therapy, physical therapy and growth hormone.
