Syndrome Presentation
Characteristics and features of HRD
H:
Hypoparathyroidism
>>
parathyroid glands control the amounts of calcium in the blood stream; decreased function of parathyroids
>>
lowered blood calcium which could cause seizures known as hypocalcemic convulsions

R:
Retardation
>>
mild to moderate MR

D:
Dysmorphism
>>
short stature caused by low secretions of the growth hormone

Deep set eyes


Prominent forehead


Depressed (pushed down) nasal bridge with beaked nose

Hearing characteristics
The Will To See: http://www.thewilltosee.com/genetics/

No hearing losses were
reported.
Speech/language
• Developmental delays.
• Learning difficulties.


Cause
• An autosomal recessive disorder linked to the long arm of chromosome 1.
• Mutations in the tubulin-specific chaperone E (TBCE) gene.

History..
• The syndrome was first reported by Sanjad et al. in 1988.

• Three years later, its inheritance was confirmed by King Faisal Specialist Hospital and Research Centre, Saudi Arabia.

• It is an autosomal recessive disorder found among the Arabian Countries that is mostly associated with consanguinity.

• It’s mainly characterized by a rare case of permanent congenital hypoparathyrodism, severe intrauterine and postnatal growth failure, intellectual deficit, seizures and dysmorphic features.

• It is very similar to the Kenny–Caffey syndrome except for the skeletal abnormalities which haven’t been reported in the cases of HRD.
