MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Striated muscle in vertebrates comprises large proteins which must be organized properly to contract efficiently. Z-lines in striated muscle are a sign of this organization, representing the ends of actin thin filaments, titin, nebulin or nebulette and accessory proteins required for structure and function. This gene encodes a protein which interacts with nebulin in skeletal muscle or nebulette in cardiac muscle and alpha-actinin. In addition, this gene product can interact with a protein with the I-band indicating it has a regulatory as well as structural function. Alternative splicing results in multiple transcript variants.

Nature of Mutation

DNA sequencing using the SOLiD technique identified a G to A transition at position 202 of the Mypn transcript in exon 1 of 20 total exons. The mutated nucleotide causes a glycine to aspartic acid substitution at amino acid 54 of the encoded protein according to NCBI record NP_892037.2. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Mypn gene encodes a 1382 amino acid that belongs to the myotilin/palladin family and contains five immunoglobin (Ig)-like domains.  The Uniprot record contains 1315 amino acids and is missing 67 amino acids from the N-terminus, including the amino acid altered by the G56D change. Myopalladin is a component of the sarcomere that tethers together nebulin (skeletal muscle) and nebulette (cardiac muscle) to alpha-actinin, at the Z lines (Uniprot Q5DTJ9).
 

The G56D change is predicted to be probably damaging by the PolyPhen program.
