Generation of two isogenic induced pluripotent stem cell lines from a 1-month-old nemaline myopathy patient harbouring a homozygous recessive c.121C > T (p.Arg39Ter) variant in the ACTA1 gene


Nemaline myopathy (NM) is a congenital skeletal muscle disorder that typically results in muscle weakness and the presence of rod-like structures (nemaline bodies) in the sarcoplasma and/or in the nuclei of myofibres. Two induced pluripotent stem cell (iPSC) lines were generated from the lymphoblastoid cells of a 1-month-old male with severe NM caused by a homozygous recessive mutation in the ACTA1 gene (c.121C > T, p.Arg39Ter). The iPSC lines demonstrated typical morphology, expressed pluripotency markers, exhibited trilineage differentiation potential and displayed a normal karyotype. These isogenic lines represent a potential resource to investigate and model recessive ACTA1 disease in a human context. Copyright © 2022 The Authors. Published by Elsevier B.V. All rights reserved.
