Ptrh2 levels were up-regulated in dystrophin deficient mdx muscle, which correlates with the elevated levels of the a7b1 integrin observed in mdx muscle and Duchenne muscular dystrophy patients. Similar to the a7 integrin, Ptrh2 expression was decreased in laminin-a2 null gastrocnemius muscle

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.
