How Baby Genes Influence Birth Weight and Diseases

Baby’s gene has been shown to have an influence on the birth weight of a child, and even with the chances and types of diseases experienced later in life. Genetic differences are┬áresponsible for differing birth weight in babies; the reason why some are born bigger and others smaller. Genetic differences is responsible for one-sixth of the variation experienced in baby’s birth weight.

How do genetic differences affect child growth?

Genetic differences are also linked to child growth. It determines whether or not the child has had an early growth, delayed growth or even developed some diseased conditions such as diabetes and cardiovascular (heart) diseases. Genetic factors determine the chances and types of certain disease conditions a child presents with later in adulthood.

Understanding the risks

Understanding these genetic factors and make up of individuals help devise and target effective strategies in preventing, controlling and treating such diseases risks. Genetic factors and differences results into 7 or 8 times of birth weight variations more that can be explained with environmental factors.

What does scientific research say?

According to a study conducted by Dr Rachel at the Exeter Medial School, small genetic differences between individuals can have great effects on birth weights and can result in poor health in later adult life. It is the child’s gene and that of the parents that combine to affect child health. Other factors such as nutrition and the environment provided for the child have influence on child’s health.

Genetic and environmental elements work together to influence growth and later diseases in a child. Babies with extremely high birth weight or low birth weight on the average have increased risk of diseases such as diabetes much later in life. There is a long-term impact of the link between above two factors (a child’s genes and the development of later life diseases).

The nutritional environment in which fetus develop affects the events that unveils in its early and later life. It can set up an individual’s body in ways that is capable of making them prone to some diseases in later life. The baby’s genetic profile and the mother’s genes both play a vital role in determining the child’s birth weight and the chances of developing diabetes or heart diseases later in life.
This is a pointer to new approaches to the prevention, control and treatment of these diseases. It will also result in great improvement in antenatal care to reduce future disease burden. About sixty genomic regions drive birth weight differences. Many of these same genomic regions are implicated in the occurrence of diabetes and cardiovascular disease conditions in later life.

There is a key role played by genetic differences in the variation in early growth and future disease risk in a child. There is therefore need for a better understanding of how the genetics profiles of both the mother and child acts together to act together to modify the baby’s birth weight and risks of diseases in later life.
