A formalization of one of the main claims of “Mutations in NGLY1 cause an inherited disorder of the endoplasmic reticulum–associated degradation pathway” by Enns et al. 20141

Abstract

Enns et al. claimed in previous work that NGLY1 deficiency is a novel autosomal recessive disorder of the ERAD pathway. We present here a formalization of that claim, stating that all things of class “NGLY1 deficiency” that are in the context of a thing of class “human” always have a relation of type “is caused by” to a thing of class “dysfunction of ERAD pathway” in the same context.

1.Introduction

Enns et al. [2] state that “NGLY1 deficiency is a novel autosomal recessive disorder of the endoplasmic reticulum–associated degradation pathway.”. We present here a formalization of the main scientific claim from this quote by using a semantic template called the super-pattern [1].

2.Formalization

Our formalization looks as follows:

CONTEXT-CLASS (“in the context of all ...”):human
SUBJECT-CLASS (“things of type ...”):NGLY1 deficiency
QUALIFIER:always
RELATION-TYPE (“have a relation of type...”):is caused by
OBJECT-CLASS (“to things of type...”):dysfunction of ERAD pathway

In the context class we use the class “human” (Q5) from Wikidata. In the subject class, we use the class “NGLY1 deficiency” from Mondo Disease Ontology. In the object class we minted a new class “dysfunction of ERAD pathway” that is related to the class “ERAD pathway” (Q21101062) from Wikidata.

3.RDF code

This is our formalization as a nanopublication in TriG format:
