Temple Syndrome/Maternal UPD 14

Test name:  Temple syndrome/Maternal UPD 14 (MatUPD 14)
Also known as: Methylation 14, Uniparental disomy (UPD) by UPD Array   

Indications: Clinical features may include prematurity, IUGR, low birth weight, short stature, hypotonia, hyperextensible joints, small hands and feet, cryptorchidism and micropenis, kyphoscoliosis, and mild truncal obesity. Mild to moderate motor delays with normal to moderate intellectual disability have been seen with Temple syndrome. Health concerns seen more commonly with Temple syndrome may include otitis media, hypercholesterolemia, advanced bone age, precocious puberty, postnatal hydrocephalus and prominent forehead.

Test Information: Temple syndrome is caused by absence of the paternal copy of chromosome region 14q32.2.
