An exceptional Albanian friends that have eight children presenting having dysmorphic enjoys and you may intellectual retardation: maternal phenylketonuria

Phenylketonuria was an inherent mistake out of amino acidic metabolic process that will trigger major injury to the individual otherwise, when it comes to maternal phenylketonuria, on the foetus. The maternal phenylketonuria problem is a result of large blood phenylalanine density while pregnant and you can gift suggestions with big foetal defects, particularly congenital cardiovascular illnesses, microcephaly and intellectual retardation.

I breakdown of a compromised Albanian lady along with her 7 children. The mother is impacted by phenylketonuria that is a compound heterozygote for a couple of pathogenetic mutations, L48S and you can P281L. This new medical diagnosis was just produced in the framework of the lady pupils, each one of whom possess at least one significant natural malformation. The original boy, 17 yrs old, possess a dual-chambered correct ventricle, spine malformations and you can epilepsy.

These girl, now eleven yrs . old, features rational retardation, microcephaly and you may epilepsy along with face dysmorphy, partial deafness and you can short prominence. The brand new eight-year-old boy is actually quite emotionally retarded and you can microcephalic. A great five-year-dated child are an early, dystrophic infant and you can exhibits intellectual retardation, dysmorphic face keeps, brachydactyly and you may clinodactyly of your own 5th hand to your both hands. Pursuing the an excellent miscarriage, our very own directory circumstances, this new youngest son on 2 years old, is microcephalic and you will psychologically retarded and you may reveals minor facial anomalies. All the students display attributes of phenylalanine embryopathy due to maternal phenylketonuria while the mommy had not been diagnosed earlier and you can, thus, never ever obtained people eating plan.


This is basically the biggest loved ones suffering from maternal phenylketonuria said during the the literary works. Maternal phenylketonuria remains problematic, especially in girl from nations instead a great neonatal evaluation system. Therefore, it is mandatory as aware towards the likelihood of maternal phenylketonuria problem in case of children towards logical has actually discussed here to end foetal wreck from inside the next sisters.


Phenylketonuria (PKU; OMIM *261600) are an enthusiastic autosomal recessive problems from phe metabolic process which can produce big damage to individual or, in the example of maternal PKU, into young children. Brand new teratogenic effects of increased maternal phe profile was initially accepted throughout the mid nineteen 1960s, immediately when techniques newborn tests and you may diet remedy for PKU was being created in extremely developed countries [Mabry et al., 1966]. Typical have within the youngsters with phe embryopathy become microcephaly, intellectual retardation and you can cardio malformation. The severity of maternal PKU syndrome try proportional to help you maternal blood phe concentrations, and you may a rigorous dietary manage just before conception and you may during the pregnancy is compulsory to prevent congenital foetal anomalies [Rouse et al., 2000].

With our case review of an exceptional Albanian family unit members, we wish to high light the issue from untreated or undiscovered PKU when you look at the mature ladies, inducing the threat of serious maternal PKU syndrome in kids.
