Prevalence of MTHFR Polymorphisms in Patients With Hypermobile Ehlers-Danlos Syndrome and Hypermobile Spectrum Disorders in a US Hypermobility Clinic.
Article in ACR open rheumatology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveHypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSD) are characterized by joint hypermobility, joint subluxations and dislocations, hyperextensible skin, and chronic and progressive multiorgan comorbidities. Diagnosing hEDS and HSD is difficult because of variable phenotypes and unknown genetic etiology. In our clinic, we observed many patients with hEDS and HSD with a high serum level of unmetabolized folate, which suggests that hypermobility may be linked to methylenetetrahydrofolate reductase (MTHFR)-mediated folate metabolism. The present study aims to examine the prevalence of MTHFR polymorphisms, C677T and A1298C, among patients with hEDS and HSD.
methodsClinical and demographic information of patients visiting our hypermobility clinic from January 2023 to July 2023 were retrospectively reviewed. Continuous variables were reported as mean ± SD and range, whereas categorical variables were reported as total count and percentage.
resultsAmong 157 patients, 93% of patients were female patients, 52.2% were diagnosed with hEDS, and 47.8% were diagnosed with HSD. Interestingly, 85% of the patients had MTHFR C677T and/or A1298C polymorphisms in heterozygous or homozygous state. MTHFR 677CT/TT genotype was present in 52.9% of cases, and 49.7% of patients had 1298AC/CC genotype. In addition,14% of patients with hypermobility exhibited MTHFR 677TT genotype, 10.2% showed 1298CC genotype, and 17.2% displayed combined heterozygosity, collectively representing 41.4% hypermobile patients with two copies of MTHFR variant alleles.
conclusionThere is a high prevalence of MTHFR polymorphisms among patients with hypermobility, which supports the hypothesis that hypermobility may be dependent on folate status.
