      VariantEvidence: Germline HSPC300, ENST197804 and FANCD2 (unclear if partial or complete) gene deletion. Study provides evidence to show that loss of HSPC300 highly correlates with the absence of ccRCC in VHL patients.

      CivicName: Exon 1-2 Deletion

    1. (a) Southern blot analysis. Genomic DNA (7 μg) was subjected to an Eco RI and Ase I double digest and hybridized with the 32P labeled VHL cDNA probe g7. The upper band corresponds to the wild-type VHL gene, while the lower band represents a VHL pseudogene (Ψ), located on chromosome 1 20. Typically, samples with a rearrangement in the VHL gene exhibit a less intense wild-type VHL band and an abnormal migrating band Lanes 2 and 9 both represent members from family 35. Patient 12 (N) is a carrier of a VHL missense mutation and can be regarded as a normal control in this analysis. (b) Multiplex ligation-dependent probe amplification (MLPA). Peak signals on the electropherogram correspond to eight different probes recognizing exon 1 (four probes), exon 2 (two probes) and exon 3 (two probes) of the VHL gene, while all other peaks represent 21 control probes for other chromosomal loci, including the FANCD2 (3 probes) and IRAK2 (one probe) genes which, similar to VHL, are located on chromosome 3p. In MLPA, a 40–50% reduction of probe signal intensity typically indicates heterozygous deletion of the corresponding genomic sequence. Deleted VHL exons are indicated by a ‘Δ’ sign followed by the number of the exon involved. Probands 36 and 35 each show a partial VHL gene deletion. Note that in proband 42 the deletion encompasses not only the entire VHL gene, but also the FANCD2 and IRAK2 loci (indicated by ‘Δc’). Proband U168 carrying a deletion of VHL exon 2 was used as a control to validate the MLPA and is not described further in this paper. In all of our patients tested, MLPA results corresponded perfectly with data from Southern blotting, with respect to the VHL exons deleted.
