Summary | This gene encodes a protein initially identified as a thyroid-specific transcription factor. The encoded protein binds to the thyroglobulin promoter and regulates the expression of thyroid-specific genes but has also been shown to regulate the expression of genes involved in morphogenesis. Mutations and deletions in this gene are associated with benign hereditary chorea, choreoathetosis, congenital hypothyroidism, and neonatal respiratory distress, and may be associated with thyroid cancer. Multiple transcript variants encoding different isoforms have been found for this gene. This gene shares the symbol/alias 'TTF1' with another gene, transcription termination factor 1, which plays a role in ribosomal gene transcription. [provided by RefSeq, Feb 2014]. |

Comment | Comment: REVIEWED REFSEQ: This record has been curated by NCBI staff. The reference sequence was derived from U33749.1, BC006221.2 and BM970838.1. On Jun 2, 2019 this sequence version replaced NM_003317.3. Transcript Variant: This variant (2) differs in the 5' UTR and coding region compared to variant 1. The resulting protein (isoform 2) is shorter and has a distinct N-terminus compared to isoform 1.
