    Summary
    Predicted to be involved in cardiac muscle contraction and skeletal muscle contraction. Predicted to be part of troponin complex. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita; distal arthrogryposis type 2B1; and intrinsic cardiomyopathy (multiple). Orthologous to several human genes including TNNI2 (troponin I2, fast skeletal type). [provided by Alliance of Genome Resources, Apr 2022]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
