Genes affected

THADA (HGNC:19217): (THADA armadillo repeat containing) This gene is the target of 2p21 choromosomal aberrations in benign thyroid adenomas. Single nucleotide polymorphisms (SNPs) in this gene may be associated with type 2 diabetes and polycystic ovary syndrome. The encoded protein is likely involved in the death receptor pathway and apoptosis. [provided by RefSeq, Sep 2016]

The c.5582G>A (p.R1861H) alteration is located in exon 38 (coding exon 37) of the THADA gene. This alteration results from a G to A substitution at nucleotide position 5582, causing the arginine (R) at amino acid position 1861 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
