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.

The c.80C>T (p.T27I) alteration is located in exon 2 (coding exon 1) of the ZBTB42 gene. This alteration results from a C to T substitution at nucleotide position 80, causing the threonine (T) at amino acid position 27 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
