A 5-month-old girl is admitted to the hospital by her pediatrician for evaluation of failure to thrive. The mother reports that her daughter has always been small and that she feels her daughter is not gaining weight as expected despite feeding her 24 ounces of a 22-calorie-per-ounce premature formula each day (135 kcal/kg per day).

She is an only child and there is no history of consanguinity. Family history is unremarkable. Physical examination reveals an alert, active, thin baby whose vital signs are normal for age. Her weight is 3.9 kg (<-3 SD from mean, according to World Health Organization Growth charts), length is 21 inches (<-3 SD from mean), head circumference is 16 inches (between 0 and -1 SD).

Further examination of her extremities reveals clinodactyly of her fifth fingers ( Fig 3 ) . She has poor head control and mild generalized hypotonia. The remainder of her …
