If so, please let me know any protocal, supplements, or diet changes that have helped. 1006C > T) were detected in a Hong Kong homocystinuric patient by Kwok et al. Gene variants are a pretty new field. DAO / HNMT - Histamine / Allergy / Leaky Gut FUT2 - Reduced intestinal microbiota CETP / USF1 / LDL-R Asn464 (rs688) / APOE IVS1+69 - Higher Methylation is the word I was looking for 🤣 when a person has a CBS gene mutation the body doesn't Methylate the sulfur in our food at a proficient rate and Oct 14, 2020 · Background Congenital hyper-homocysteinemia (HHcy) is caused by a defective cystathionine β-synthase (CBS) gene, and is frequently associated with dyslipdemia. Individuals with a CBS mutation (elevated activity) often have high levels of taurine and ammonia and low cystathione and homocysteine (2,3). For example, the relatively high value of 1:58,000 is for Northern Ireland and is due to the frequency of the G307S B6-nonresponsive mutation. Ammonia is extremely damaging to the brain and can cause loss Feb 4, 2016 · CBS defects are upregulations where the enzyme works too fast which results in low levels of cystathionine and homocysteine and high taurine and ammonia. Oct 2, 2024 · The disorder is caused by changes (mutations) of a gene that regulates the production of the CBS enzyme. Jan 15, 2014 · CBS deficiency incidence varies from region to region. In one study, three of 13 CBS deficient patients had normal CBS activity in fibroblasts (Mendes et al 2013 ). You're not reporting getting a stress/anxiety response from methyl supps, so that's an additional clue that it's not a problem. However, it is important to highlight that no clear genotype–phenotype correlation is established for most CBS mutations. Although having BHMTs is supposed to exacerbate the situation and even cause a CBS problem if you don't have the SNP. There are numerous SNPs within CBS. Maybe try an elimination diet (cheapest) for a month, cutting out gluten, dairy, sulfites and see how you react when you add them back in which would suggest something gut related. Basically people with this type of mutation create an excess of sulphur and if you also have a snp in the SUOX gene, you have trouble converting sulfite into sulfates. CBS Mutation. Your neurotransmitter profile fits with your CBS mutations. Methyl donors may also give you side effects. This means the enzyme works too fast. Anxiety and panic attacks Jan 24, 2015 · Well, not a lot. Edit: they’ve only been doing this diet since January 1st. dirtygenes. It is also a target for therapeutic interventions in diseases with sulfur metabolism disruption. Apr 10, 2012 · Some patients benefit from supplementing their diet with vitamin B 6, a cofactor that aids CBS’s enzymatic activity, but it depends on which mutation they carry. Elevations in CBS pathway activity may be more likely to occur in individuals who are ++, or +/- in the following genetic mutations: CBS C699T; CBS A360A; CBS N212N; Even without a CBS mutation, there may still be elevated CBS/transsulfuration activity. CBS (cystathionine beta synthase) gene mutations mean a person cannot effectively metabolize and eliminate ammonia, among other issues. Yasko, a homozygous mutation of BHMT 01, BHMT 02, BHMT 04, can produce results similar to one with a CBS upregulation even if you don't have a CBS upregulation. Some mutations are pyridoxine responsive, some not [1-58]. To identify molecular basis underlying Oct 10, 2018 · My First post to this amazing community. A few supplements may provide an added benefit but they will not help if you do not do the elimination diet. Hydrogen sulfide (H2S) may need to be the focus with CBS, not homocysteine. CBS mice rarely live past two weeks and exhibit a variety of abnormalities, which include growth retardation, severe hepatopathy, vascular abnormalities, dislocation of the eye‐lens and skeletal deformities (Watanabe et al Mar 20, 2020 · The early detection of homocystinuria along with low protein and methionine-restricted diet is the best treatment approach for all types of homocystinuria patients. People with a CBS mutation benefit from a low sulfur diet. Having a mutation greatly affects how much folate … What You Need To Eat (And Avoid!) For MTHFR Read More » CBS (cystathionine beta synthase) gene mutations mean a person cannot effectively metabolize and eliminate ammonia, among other issues. CBS defects are actually upregulations. Dec 9, 2023 · Whole exon sequencing showed a mutation of the cystathionine beta-synthase (CBS) gene (c. Jun 18, 2016 - The cystathione beta synthase enzyme is a key part of the transsulfuration pathway. Individuals with a CBS mutation will produce more sulfur end products from the methylation cycle. The COMT++ The impact of genotype (e. 19 , however, it is so far the only report describing mutations in the Secondly, 191 pathogenic CBS mutation sites have been reported in cases of patients with ectopia lentis, connective tissue lesions, and CNS involvement who are unresponsive to vitamin B6 treatment cystathionine beta synthase (CBS) or remethylation defects (that require specific management, like protein-restricted diet and vitamin therapy for life). Missense mutations in CBS are the major cause CBS gene dysregulation may result in oxalate formation because it needs vitamin B6 and its role in glutathione formation.
