monogenic autosomal recessive trait
.

Three of them—
T-box transcription factor-22 (TBX22), poliovirus receptor-like-1 (PVRL1)
, and interferon regulatory factor-6 (IRF6)—are responsible for causing X-linked cleft palate, cleft lip/palate–ectodermal dysplasia syndrome, and Van der Woude and popliteal pterygium syndromes, respectively; they are also …
What is Pierre Robin Syndrome?
Pierre Robin sequence is also known as Pierre Robin syndrome or Pierre Robin malformation. It is
a rare congenital birth defect characterized by an underdeveloped jaw, backward displacement of the tongue and upper airway obstruction
. Cleft palate is also commonly present in children with Pierre Robin sequence.
Why is cleft palate so common in Asia?
“In the past in some Asian countries, it’s been because of
a deficiency in folic acid
,” Dr Prasad said. “A deficiency in folic acid can cause increased risk of neural tube defects, which can increase risk of cleft palate or craniofacial disorders,” he said.
Which syndrome most often causes cleft lip?
The most common condition to be associated with a cleft is
Pierre-Robin Sequence (PRS)
. PRS is usually detected at birth because these babies can be born with an unusually small chin.
Does cleft palate affect the brain?
The cognitive deficits associated with isolated clefts of the lip and/or palate (ICLP) are
less severe
, but the functional consequences of these deficits should not be underestimated. The pattern of cognitive deficits reported in ICLP is a lower than average general IQ
2
with specific deficits in language function.
Why is cleft palate bad?

are unknown

Do you grow out of Pierre Robin syndrome?
Most children with Pierre Robin Sequence
grow up normally
, even if they start their lives with quite severe problems. All babies with Pierre Robin Sequence will have some difficulties, but these will vary from child to child. Some have no problems with breathing and only minor feeding difficulties.
