Comments: Found as a heterozygote. This mutation does not seem to affect the stability nor the function of the variant. Its chromatographic profile suggests a probable interference during the monitoring of glycated haemoglobin (HbA1c).

We follow the HGVS sequence variant nomenclature and IUPAC standards.
