Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at position 4430 of the Myh4 transcript in exon 30 of 39 total exons. The mutated nucleotide causes an aspartic acid to glycine substitution at amino acid 1447 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Myh4gene encodes the 1939 amino acid myosin heavy chain and is necessary for muscle contraction (Uniprot Q5SX39). Homozygotes for a targeted null mutation exhibit decreased growth and muscle defects including reduced muscle mass, muscle fiber loss, compensatory fiber hypertrophy, and impaired strength.

The D1447G change is predicted to be benign by the PolyPhen program.
