Fig. 4From: Novel gene mutation in von Hippel-Lindau disease – a report of two casesVHL gene and testing results of case 1. a The top row shows the wild-type human VHL DNA sequence segment of 721–770 from the NCBI database (NM_000551.3). The nucleotide database includes EST and GSS sequences. The bottom row shows the deletion of the GACTGGA sequence in the VHL gene of the subject. b Genetic testing results of the patient’s VHL gene, indicating the deletion of the GACTGGA sequence, leading to an amino acid Arg-177 change in case 1Back to article page
