LOINC Code


LOINC code94403-3
nameCHRNA3 gene c.645C>T [Genotype] in Blood or Tissue by Molecular genetics method Nominal
descriptionThe patient's genotype for the c.645C>T (D398N, rs1051730) variant in the CHRNA3 (nicotinic acetylcholine receptor alpha 3 subunit) gene. The rs1051730(T) allele is associated with nicotine dependence, cigarette consumption, smoking cessation, lung cancer risk, and COPD.[PMID: 26751916]
