Green List (high evidence)

The guideline includes MPS type I (Hurler), other MPS disorders in Table 1, and the diagnostic test Leukocyte MPS enzymes, genetic analysis for this. Green genes on the Mucopolysaccharideosis, Gaucher, Fabry (Version 1.2) gene panel version 1.2 (code 75) that included a Mucopolysaccharidosis phenotype were added to this panel to represent the genes that would be included on the test from the guideline.
Created: 30 Apr 2019, 4:48 p.m.
This gene was included in Table 1 for a diagnostic test from the MetBioNet guideline - see publications field for URL to the guideline.

I don't know

GM1-gangliosidosis, type I OMIM#230500; GM1-gangliosidosis, type II OMIM#230600; GM1-gangliosidosis, type III OMIM#230650; Mucopolysaccharidosis type IVB (Morquio) OMIM#253010
Created: 25 Mar 2019, 4:30 p.m.
OMIM: only listed with HCM/DCM in GM1-gangliosidosis, type I - infantile form (not type II or III or Morquio disease) But quite a few pathogenic classed variants on HGMD are associated with the infantile form. But cardiomyopathy only seen in a subset of patients not a key feature
