This study reports 1,548 germline and somatic mutations from 945 VHL families, including 30 previously unpublished kindreds from The Netherlands (six novel mutations). This mutation was detected by direct sequencing and MLPA. This nonsense mutation (p.F148* (c.443_455delinsA)) was found in as a sporadic germline in a VHL case with multiple bilateral retinal angiomas (case no. 401). The case was suspected to be de novo but this could not be confirmed. There is very strong evidence of pathogenicity in the form of a nonsense variant in a gene where loss-of-function is known mechanism of disease (ACMG code: PSV1).
