DeCure for Nemaline myopathy 5B, autosomal recessive, childhood-onset

DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for nemaline myopathy 5B, autosomal recessive, childhood-onset — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.

The disease map

Disease moduleNemaline myopathy 5B, autosomal recessive, childhood-onset maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for nemaline myopathy 5b, autosomal recessive, childhood-onset is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

Investigations on the Inheritance of Nemaline Myopathy

AbstractExtensive investigations on 11 patients with nemaline myopathy (six index patients, five relatives), their parents, and some healthy relatives were carried out. In one family, nemaline myopathy was inherited as an autosomal dominant trait. No linkage between the locus of nemaline myopathy and the locus of seven informative genetic markers (out of 25 investigated markers) was found. In two families an autosomal recessive inheritance could be demonstrated with certainty. In these families, both parents of each index patient had rods and an increased number of fibers with internal nuclei. In two other families, one or both parents of each index patient had an increased number of fibers with internal nuclei, also indicating the possibility of autosomal recessive inheritance in these cases. It can be concluded that there are two types of nemaline myopathy. However, these two diseases could not be separated on a clinical or histopathological basis.

Clinical and molecular analysis of four unrelated Chinese families with pathogenic KLHL40 variants causing nemaline myopathy 8

AbstractAbstract Homozygous or compound heterozygous variants in the KLHL40 gene cause nemaline myopathy 8 (NEM8), a severe autosomal recessive muscle disorder characterized by prenatal polyhydramnios, fetal akinesia or hypokinesia, joint contractures, fractures, respiratory failure and dysphagia. Currently, 46 individuals with NEM8 have been described in the literature, and 30 variants in KLHL40 have been identified. Here, we reported five individuals from four unrelated Chinese families who presented common features of nemaline myopathy and infrequent clinical characteristics. Whole-exome sequencing (WES) was used to identify the causative gene. WES identified a recurrent missense variant c.1516A>C (p. Thr506Pro) and a novel frameshift variant c.543del (p. Ser182Profs*17) in KLHL40 in patient 1, a nonsense variant c.602G>A (p. Trp201*) and a missense variant c.1516A>C (p. Thr506Pro) in KLHL40 in patient 2, and homozygous variant c.1516A>C (p. Thr506Pro) in KLHL40 in patient 3 and both siblings (patients 4 and 5), all of which were confirmed by Sanger sequencing. Next, we estimated the incidence of this disorder in the southern and northern Chinese population to be 4.59/10 6 and 2.95/10 6 , respectively, based on the cumulative allele frequency of pathogenic variants in internal database. The results of our study expand the mutation spectrum of KLHL40 and enrich our understanding of the clinical characteristics of NEM8. Genetic counseling was provided for the four families involved in this study. Given the severity and the relatively high incidence of this condition, we strongly suggest that KLHL40 be incorporated into a carrier screening panel for the Chinese population.
