No detectable RNA was found in the normal thyroid tissue or thyroid cancer in the Human Protein Database, although a low level of HABP2 protein was detected in normal thyroid.52 In contrast, ZNF23 was expressed at low levels by essentially all papillary thyroid cancers, consistent with its role as a transcription factor. The gene discussed is HABP2; the disease is thyroid gland papillary carcinoma.
