Analyze Your Genetic Variants For Choline Deficiency
Choline deficiency - An Introduction
What is choline?
Choline is an essential, water-soluble, vitamin-like substance that is required for maintaining the structure, integrity, and signaling functions of the cell membranes, for neurotransmission and lipid transportation.
It also acts as a source of methyl groups and is?essential for fetal development?during pregnancy.
Though choline can be synthesized in the body, you need to acquire some through your diet as well, to avoid deficiency.
The choline requirement varies with age.
According to the?National Nutrition Research Institute of North Carolina, only a mere 10% of the population has sufficient intake of choline, while the others are deficient.
Inadequate choline in the body can lead to many problems, including cardiovascular diseases, neuropsychiatric diseases such as Alzheimer’s and schizophrenia, and degenerative diseases like osteoporosis.
Functions of choline
Choline is an essential component in the diet because it performs many crucial roles in the body.?
What are the symptoms of choline deficiency??
The symptoms of choline deficiency include:
Choline deficiency:?What’s the genetic link?
Gene 1:?MTHFD1
The?rs2236225?is an SNP found in the?MTHFD1?gene on chromosome number 14.
It is involved in?folate metabolism.
Choline requirements are altered in polymorphisms of the?MTHFD1?or methylenetetrahydrofolate dehydrogenase 1 gene.
A study done in Canada showed that the mutation in the?MTHFD1?could increase the risk of heart defects.
Caucasian mothers with rs2236225 (C, T) and rs2236225 (T, T) alleles were at an increased risk (of about 1.5-1.7 times) of having children compared to mothers with no (T) alleles.
However, one must be cautious while reading results as the studies have statistical uncertainties.
Gene 2:??PEMT
A part of the choline requirement of the body can be satisfied by the synthesis of?phosphatidylcholine?that is catalyzed by?PEMT?or?phosphatidylethanolamine N-methyltransferase?in the liver.
The polymorphisms may alter choline requirements in the?PEMT?gene.
The SNP?rs12325817?in the promoter region of the?PEMT?gene, a large percentage of carriers of the C allele developed organ dysfunction when on a low choline diet.
Also, sexual differences were observed in the effect of?PEMT?gene rs12325817, and the SNP may alter the estrogen responsiveness of the promoter.
Unusual estrogen regulation of?the PEMT?gene results in choline deficiency-associated liver dysfunction.
Effect on women with the following allele combination in SNP rs12325817.
The presence of the C allele puts one at risk of developing organ dysfunction.
What causes acetylcholine deficiency?
The neurotransmitter acetylcholine is synthesized from choline.
So, a deficiency of choline leads to a lack of acetylcholine.
Though our body can synthesize its choline, we need to eat choline-rich foods to maintain its optimum levels in the body.
So, inadequate dietary intake of choline is the biggest reason for the deficiency of choline and acetylcholine.
Note:
The ideal requirement of choline for everyone varies with age.

Adult men?should be able to consume?550mg?per day, and?adult women?need to consume?425mg per day.
The choline needs for women increase during?pregnancy?to?450mg per day?and even more during?breastfeeding?to?550mg per day.
Does acetylcholine affect mood?
The acetylcholine system plays an essential role in mood swings and also contributes to mental conditions like depression.
It was found that the brains of depressed individuals tend to have higher concentrations of acetylcholine.?
The relationship between mood changes due to the withdrawal from smoking and acetylcholine has been the basis for studying its effect on mood changes.
Does choline cause anxiety?
Choline deficiency has many different effects on our bodies.
It improves brain functioning, memory, cognitive function, learning, and memory.
However, a deficiency of the substance can lead to effects such as depression, anxiety, mood disorder, and Alzheimer’s.
Does choline help with weight loss??
Yes, choline helps with weight loss. In competitive sports events, individuals are expected to gain and lose weight in a short time.
Choline supplementation helps in these situations when the athlete has to lose weight rapidly.
The reason for this is that choline plays a vital role in fat metabolism.
Dietary sources of choline
The dietary sources of choline include:
Vegetables that are rich in choline are:
Some fruits that contain choline are:
Health risks associated with choline deficiency
The inadequate consumption of choline can lead to high homocysteine and all the risks associated with?hyperhomocysteinemia.
Note:
Certain groups of people are at an increased risk of choline deficiency. These include:
What are the effects of excess choline in the body?
While it is essential to maintain an adequate amount of choline in the body at all times, an excessive amount of choline can be harmful too.
The harmful effects of excess choline include:
However, one can take a few precautions to avoid excessive choline intake.
A word of caution
Before taking choline supplements, it is highly recommended to read the quantity of choline and if in doubt, seek the advice of your doctor.
