Genes affected
ZBTB42 (HGNC:32550): (zinc finger and BTB domain containing 42) The protein encoded by this gene is a member of the C2H2 zinc finger protein family. This protein is predicted to have a pox virus and zinc finger (POZ) domain at the N-terminus and four zinc finger domains at the C-terminus. In human and mouse, the protein localizes to the nuclei of skeletal muscle cells. Knockdown of this gene in zebrafish results in abnormal skeletal muscle development and myofibrillar disorganization. A novel homozygous variant of the human gene has been associated with lethal congenital contracture syndrome, an autosomal recessive disorder that results in muscle wasting.
