Congenital myopathy
Gene: FLNCComment on list classification: Amber gene recommended by Anna Sarkozy as a result of GLH Test Group prior to sign off. Four unrelated patients with cardiomyopathy, arthrogryposis, and a limb-girdle pattern of skeletal muscle weakness at birth or during the first year of life harboured de novo missense variants; three of these patients had p.Ala1186Val.

Promoted 22/02/2017 after curation discussion and further review with members of the Genomics England curation team. Participants who are offered this panel will automatically be offered the following three panels: 1) Congenital muscular dystrophy 2) Congenital myasthenia and 3) Paediatric motor neuronopathy as this will cover a large range of differentials for a weak infant, for where the strict inclusion criteria are not applicable in view of the availability of muscle biopsy testing in peripheral paediatric units.
This gene has been classified as Red List (Low Evidence).
