Congenital hypoparathyroidism, seizure, extreme growth failure with developmental delay and dysmorphic features--another case of this new syndrome.

A 4-year-old Saudi female child with extreme failure to thrive, striking dysmorphic features, developmental delay, congenital hypoparathyroidism, UTI, seizures, chronic otitis media, chronic non-specific gastroenteritis and repeated life-threatening infections was followed from birth. She was the product of first-cousin consanguineous marriage. She had striking facies with frontal prominence, deep-set eyes, depressed nasal bridge, beaked nose, long philtrum with thin upper lip, micrognathia, large floppy ears, bifid uvula, and growth retardation with SD score less than -2 for height, weight and head circumference. We believe these features which include congenital hypoparathyroidism, severe growth failure and developmental delay in the absence of chromosomal abnormality represent a newly described genetically determined syndrome.
