The problems of prematurity grew very preterm to very low birth weight babies with special problems. In certain ethnic populations, such as Ashkenazi Jews (Jews of central and eastern European ancestry), the rate of inherited metabolic disorders is higher.

While there were nurseries, the need for intensive care nurseries became evident in the 1960s, and the need for perinatal care of pregnant mothers also grew as a result of metabolic problems of the mother, intrauterine positioning of the fetus, and increasing numbers of teen age pregnancies as well as nutritional problems of the mother. Hundreds of inherited metabolic disorders have been identified, and new ones continue to be discovered.

Week 5 is the start of the “embryonic period.” This is when all the baby’s major systems and structures develop. Tissue grows that will the baby’s spine and other bones. Phenylketonuria (PKU): Deficiency of the enzyme PAH results in high levels of phenylalanine in the blood.

The embryo’s cells multiply and start to take on specific functions. Blood cells, kidney cells, and nerve cells all develop. Baby’s heart continues to grow and now beats at a regular rhythm. Mental retardation results if the condition is not recognized.

Because it’s impossible to know exactly when conception occurs, gestational age is measured from the first day of the mother’s last menstrual cycle to the current date. A normal gestation lasts anywhere from 37 to 41 weeks. Nerve damage results, and the urine smells like syrup.

A total of 18 different variations in the GALT gene were found in the patient cohort: 12 missense, 2 frameshift, 1 nonsense, 1 deletion, 1 silent variation, and 1 intronic. Increasing evidence indicates that dysfunction of NMDA receptors (NMDARs) at excitatory synapses is associated with ASDs.

In support of this, human ASD-associated genetic variations are found in genes encoding NMDAR subunits.

No neonatal deaths due to galactosemia complications occurred after the introduction of the neonatal screening program. However, some fall onto common pathways, including synaptic function and chromosome remodeling, suggesting that core mechanisms may exist.

However, despite the early diagnosis and dietary treatment, the patients with classical galactosemia showed one or more long-term complications. Abnormalities and imbalances in neuronal excitatory and inhibitory synapses have been implicated in diverse neuropsychiatric disorders including autism spectrum disorders (ASDs).Functional enhancement and suppression of m Glu R5 are associated with fragile X syndrome and tuberous sclerosis, respectively, which share autism as a common phenotype.
