Red List (low evidence)

Comment on list classification: There is only one patient reported so far with early-onset myopathy and monoallelic HNRNPA1 variants. Hence, this gene should remain red with the current evidence.

Panel Version: 7.61
PMID:39121134 (2024) reported a female patient with early childhood onset, rapidly progressive generalized myopathy including ultrastructural findings in line with a proteinopathy. Between 3 and 5 years, she developed progressive generalised muscle weakness and atrophy affecting her extremities, limb girdle and trunk muscles accompanied by worsening of gait instability, myopathic facies and difficulties chewing and swallowing. She was identified with a 85-bp deletion in HNRNPA1 gene (c.684_751 + 17del).

Red List (low evidence)

Comment on list classification: There are at least 7 unrelated individuals reported in literature with monoallelic variants in HNRNPA1 that presented with distal myopathy (PMIDs 34291734;34722876;35550112;39072769). As disease onset is either juvenile or in early adulthood, this gene is not in scope for Congenital myopathy and should remain Red.

panel promoted to version 1

Helen Brittain (Genomics England Curator)

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.
