Population

21 patients from 14 families with severe, usually lethal, nemaline myopathy (NM), and a zebrafish model

Design

Preclinical

Authors

Discussion

LMOD3 testing may aid severe NM diagnosis; leaves open targeted therapies pending validation.

Population

21 patients from 14 families with severe, usually lethal, nemaline myopathy (NM), and a zebrafish model

Intervention

Whole-exome sequencing (WES) and Sanger sequencing; knockdown of lmod3 in zebrafish

Outcome

Identification of pathogenic genetic variants and functional/pathological phenotypes of lmod3 knockdownsurrogate

Mutations in LMOD3 cause severe congenital nemaline myopathy by disrupting sarcomeric thin filament organization.

Yuen et al. (2014) studied this question.
