Duchenne muscular dystrophy

Library compounds whose LINCS consensus expression profiles most strongly anti-correlate one transcriptional signature associated with Duchenne muscular dystrophy, after a cytotoxicity-alignment filter and clinical-maturity ranking. Compounds our structural screen flags are labelled below rather than hidden. This is a property of that signature, not of the disease. Computational and hypothesis-generating, pending wet-lab. Method & limits →

Not tested. Twenty-three indications in our corpus hold two independently derived signatures. Comparing the twelve top candidates from each: 14 pairs shared no compound, 6 shared one, 3 shared two — indistinguishable from the 3,173 pairs built from different indications, where 60.1% likewise share nothing (p = 0.92, two-sided). But in every one of those pairs one signature was far too shallow to measure anything, so that outcome was expected before the test was run. It is not evidence that the method fails; it is evidence that we never ran a test capable of succeeding. Treat the names below as leads from one measurement, not as candidates for the disease.

Signature availability Duchenne muscular dystrophy

This indication is not ranked and not for sale. What follows is the measurement we hold and why it is not enough, published because it is the part of this work most likely to be useful to someone attempting the same thing.

Signature	CREEDS dz:674 (GSE6011, human)
Organism	human
Genes in the signature	595
Of those, inside the LINCS-978 landmark set	49
Position in our corpus of 118 signatures	17th percentile

The signature is not small — it is measured on a different gene space. It carries 595 genes, but our score is a rank correlation computed only over those it shares with the 978-gene LINCS landmark set, and that intersection is 49. At that depth, the result could not be separated from a signature whose gene labels had been shuffled — that is, from no disease information at all.

What would change this

A signature for this indication measured on a platform that overlaps the landmark set more deeply. Our floor is 300 genes; 200 is the deepest point at which we have actually measured reliability. We cannot tell you which genes would matter most here — that would need a curated disease-gene map for this indication, which we do not hold and are not going to assert. If you have a deeper signature for this disease and want it scored against our library, that is a conversation we are glad to have.

Ranking withheld for this indication

Our reversal score is a rank correlation computed over the genes this disease signature shares with the LINCS-978 landmark set. For Duchenne muscular dystrophy only 49 genes overlap, against a median of 916 across our corpus. A correlation over so few genes is not a reliable measurement, so we are not ranking or selling candidates for this indication until the signature is rebuilt against the landmark space. The candidate names above are shown for transparency and are not ordered by a trustworthy score.
