Comment on list classification: Only mild contractures described in 1/2 individuals with variants in this gene. Therefore, there is only enough evidence for a RED rating on this panel at present. These cases would still expected to be picked up via the 'Congenital myopathy' or 'Fetal anomalies' routes for which this gene is Green.

- PMID: 30215711 (2018) - Predominant phenotype is severe hypotonia and respiratory failure from birth. 2 patients are reported: one had polyhydramnios and normal fetal movements, with mild flexion contractures at birth. The other had normal liquor volume, reduced fetal movements, and no contractures.
