What's a GeneRIF?

But the great majority of evidence is consistent with these TMCs as pore-forming subunits of the long-sought hair-cell transduction channel. [review]
Title: Are TMCs the Mechanotransduction Channels of Vertebrate Hair Cells?
Autozygosity by descent analysis of 2 markers bordering the TMC2 gene allowed us to rule out its association with deafness within these families.
Title: TMC1 but not TMC2 is responsible for autosomal recessive nonsyndromic hearing impairment in Tunisian families.

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.
