For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates – infants weighing less than 2,500 g (5 lb 8 oz) – are small for gestational age. [citation needed] There is an 8.1% incidence of low birth weight in ...

Growth deficiency or failure to thrive: slow fetal growth low birth weight or height, small head circumference (microcephaly) [14] [a] Congenital malformations of lips: short palpebral fissure lengths, smooth philtrum, and thin upper lip. [15] [b] Nervous system damage: Clinically significant structural neurological, or functional impairment [c]
Mothers of infants with this disorder usually have uneventful pregnancies and deliveries, with the child appearing normal and within typical birth weight and length ranges. Infants with GLUT1 deficiency syndrome have a normal head size at birth, but the growth of the brain and skull is slow, in severe cases resulting in an abnormally small head ...
It is characterized by intrauterine growth restriction and postnatal dwarfism with a small head, narrow bird-like face with a beak-like nose, large eyes with down-slanting palpebral fissures, [3] receding mandible and intellectual disability. A mouse model has been developed. [4] This mouse model is characterized by a severe deficiency of ATR ...
