Humans have several FMO genes, but only mutations in Alaris Health At The Fountains 595 You can make an appointment over the phone, or through an online process. Although there is not yet a clear reason for this, researchers suggest that female sex hormones, such as estrogen and progesterone, could play a role. Some diets and pregnancy can also cause this symptom. The condition is caused by a homozygous mutation in the FMO3 (flavin monooxygenase 3) gene coding for the enzyme that converts TMA (trimethylamine) to trimethylamine N-oxide. [1] (2010). An electronic catalog of human genes and genetic disorders, developed by the National Center for Biotechnology Information (NCBI). Christodoulou, J. The developing embryo (the combined egg and sperm) can then be tested for the genetic changes in the FMO3 gene that cause trimethylaminuria in their family. Autosomal means the gene is located on any chromosome except the X or Y chromosomes (sex chromosomes). BIOCHEMICAL GENETICS . Some people may have trimethylaminuria because they have an inherited metabolic condition that blocks the enzyme from breaking down trimethylamine. The urine test can also identify people who are carriers, which means they have one copy of the FMO3 gene with a mutation and one without, but only if the procedure described above is followed.

Avoiding people because theyre embarrassed about their condition. Trimethylaminuria is a very rare condition. One of these copies comes from the mother in the egg and the other copy comes from the father in the sperm. Trimethylaminuria is usually inherited in an autosomal recessive fashion, which means that two non-functioning FMO3 genes are usually needed for a person to have symptoms. Amberger, J. (2014). Background: Trimethylaminuria is a rare disorder characterised by foul odour from bodily fluids and breath.
