Sex-specific risk loci and modified MEF2C expression in ALS
medrxiv(2024)
摘要
Significantly more men develop amyotrophic lateral sclerosis (ALS) than women, and heritability is not uniform between male and female transmissions, together suggesting a role for sex in the genetic aetiology of the disease. We therefore performed sex-stratified genome-wide and transcriptome-wide analyses of ALS risk, identifying six novel sex-specific risk loci including MEF2C , which shows increased expression in female ALS motor neurones. X-chromosome analysis revealed an additional risk locus at IL1RAPL2 .

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.
Yes
The details of the IRB/oversight body that provided approval or exemption for the research described are given below:
Please see attached .tsv file detailing IRB approval as requested
I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.
Yes
I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).
Yes
I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
Yes
The GWAS summary statistics generated in this study will be made publicly available upon publication in the NHGRI-EBI GWAS Catalog at https://www.ebi.ac.uk/gwas/ (for female, male and X chromosome meta-analyses, respectively) and through the Project MinE website (https://www.projectmine.com/research/download-data/).
