HPIi004-B

Flagged for further review

Alternative Names: iPS-5964-R6

Details

Description

This induced pluripotent stem cell line was derived by using sendai viral vectors to reprogram an immortalised lymphoblastoid cell line generated from a male Nemaline Myopathy 3 patient. HPIi004-B is described as having a normal karyotype and a homozygous variant in the ACTA1 gene. This variant was also present in the donor lymphoblastoid cell line. Expression of OCT4, NANOG, SOX2, CRIPTO, TRA-1-60 and SSEA-4 in undifferentiated cells, and directed differentiation to endoderm, mesoderm and ectoderm have been reported.

Age: Neonate

Biological Sex: Male

Disease: MONDO:0008070
Label: congenital myopathy 2a, typical, autosomal dominant
Definition: An inherited myopathy caused by mutations in the ACTA1 gene, encoding actin, alpha skeletal muscle. The phenotype is highly variable, and as such attempts at classification by clinical features is not optimal. Generally, affected individuals have generalized muscle weakness, typically involving proximal muscles, the face, bulbar and respiratory muscles.
