LIMB-GIRDLE MUSCULAR DYSTROPHY 2B/MIYOSHI MYOPATHY TYPE 1- DYSFERLIN GENE MUTATION LGMD2B/MIYOSHI IPS CELL LINES (INCLUDING AFFECTED, CARRIER, AND CONTROL CELL LINES) FROM JAIN FOUNDATION
This iPSC collection, which was deposited by the Jain Foundation, serves as a model for the dysferlin gene mutation. Mutations in the dysferlin gene are found in a group of diseases known as limb-girdle muscular dystrophy type 2B and Miyoshi myopathy type 1 (LGMD2B/MMD1). The affected cell lines available in this collection carry two heterozygous alleles with genetic mutations in dysferlin.
This collection consists of iPSC clones derived from 3 affected donors who are dysferlin protein deficient, 1 carrier who is heterozygous for a dysferlin mutation, and 1 unrelated control.
The provider notes the following: The donor for the HZ line has been genetically confirmed to be heterozygous, and to express dysferlin at a lower level than the donor for the WT line. However, for reasons that are unclear, the Romeo antibody (Epitomics #5140-1) which targets the N-terminal region of dysferlin, does not show reactivity with muscle cells derived from the HZ line. An alternate dysferlin antibody (Leica NCL-Hamlet) targeting the C-terminal region of dysferlin does show reactivity with muscle cells derived from the HZ line. Bear this in mind when designing experiments using the HZ iPSCs.
