DeCure for Hereditary spastic paraplegia 57

DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for hereditary spastic paraplegia 57 — 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 moduleHereditary spastic paraplegia 57 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 hereditary spastic paraplegia 57 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.

Molecular view

trafficking from ER to golgi regulator (TFG)TFG is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to

Two consanguineous families with complicated autosomal recessive hereditary spastic paraplegia were mapped to a new locus on chromosome 8p12-p11.21, between markers D8S1820 and D8S532, with a combined lod score of 7.077 at marker D8S505. Affected individuals in one family had thin corpus callosum and mental retardation; in the other family two of three affected individuals had epilepsy. The candidate genes neuregulin and KIF13B lie within this 9 cM interval. This locus is distinct from the previously identified SPG11 locus on chromosome 15q13-q15 for hereditary spastic paraplegia with thin corpus callosum.

Hereditary spastic paraplegia is often autosomal dominant, but autosomal recessive forms exist. In a series of six families with 26 affected members, all initial referrals were children with slowly progressive paraplegia, slightly delayed motor milestones, normal intellect, and no history of perinatal cerebral event. Treatment consisted of tendon lengthenings when necessary. Recognition of the hereditary pattern is described as key to management.

In Caucasian populations, heterozygous Spastin mutations (SPG4) account for the majority of HSP patients, with clinical manifestation typically in the third or fourth decade. Childhood manifestation is more common in less frequent forms such as SPG3a or complicated HSP like SPG11. No specific drug treatment is mentioned in any of these abstracts.

What is still missing: no drug has been tested in any clinical trial for this specific HSP57 locus; no patient stratification by genotype is available; no funding for preclinical or clinical work on this rare subtype has been reported.

A novel locus for hereditary spastic paraplegia with thin corpus callosum and epilepsy

AbstractBACKGROUND: Hereditary spastic paraplegia (HSP) are classified clinically as pure when progressive spasticity occurs in isolation or complicated when other neurologic abnormalities are present. At least 22 genetic loci have been linked to HSP, 8 of which are autosomal recessive (ARHSP). HSP complicated with the presence of thin corpus callosum (HSP-TCC) is a common subtype of HSP. One genetic locus has been identified on chromosome 15q13-q15 (SPG11) for HSP-TCC, but some HSP-TCC families have not been linked to this locus. METHODS: The authors characterized two families clinically and radiologically and performed a genome-wide scan and linkage analysis. RESULTS: The two families had complicated ARHSP. The affected individuals in Family A had thin corpus callosum and mental retardation, whereas in Family B two of three affected individuals had epilepsy. In both families linkage analysis identified a locus on chromosome 8 between markers D8S1820 and D8S532 with the highest combined lod score of 7.077 at marker D8S505. This 9 cM interval located on 8p12-p11.21 represents a new locus for ARHSP-TCC. Neuregulin and KIF13B genes, located within this interval, are interesting functional candidate genes for this HSP form. CONCLUSION: Two consanguineous families with complicated autosomal recessive hereditary spastic paraplegia were clinically characterized and genetically mapped to a new locus on 8p12-p11.21.

Hereditary Spastic Paraplegia

AbstractHereditary spastic paraplegia is a genetically transmitted disease that is usually autosomal dominant. Characterized by a slow progression of spastic paraparesis, it is frequently misdiagnosed as cerebral palsy. Our experience consists of six families with a total of 26 affected members. All initial referrals were children with a slowly progressive paraplegia. Each child was noted to have slightly delayed motor milestones, normal intellect, and no history of perinatal cerebral event. Each child was treated when necessary with appropriate tendon lengthenings. Recognition is the key to management. A careful patient and family history will reveal the hereditary nature of the disease and help develop treatment plans.

Mutation Spectrum and Infantile Manifestation in Hereditary Spastic Paraplegia

AbstractAims: Hereditary spastic paraplegia (HSP) is genetically heterogeneous and clinically characterized by gait impairment because of weakness and spasticity of the lower limbs. In Caucasian populations, heterozygous Spastin mutations account for the majority of patients (SPG4) with predominant clinical manifestation within the third or fourth decade of life. A clinical manifestation during childhood is well known, but more common in less frequent forms such as SPG3a or complicated HSP, for example, SPG11.
