Model: Zebrafish

Gene: RERE

Gene alteration: The genetic change responsible for the babyface (bab) phenotype was identified. there are two bab alleles; babtb210 is caused by rerea Y361X, and babtw220c is caused by rerea Y394X

Model phenotype: Both models both display nearly identical phenotypes (Schilling et al.,1996) including a small head and eyes, severely reduced pharyngeal arches and pectoral fins, and enlarged ear capsules (Fig. 1A,B).

NonHumanModel Mus musculus

GeneAlteration oligonucleotide-directed mutagenesis of lambda phage to make a p.T494M vector to inject mice.

Variant: c.534delAGTT (p.L178fs27X) in both alleles

CAID: CA560766108

gnomAD: MAF 0.000008937, European (non-Finnish), gnomAD variant ID: 5-73992535-CAGTT-C

VariantEvidence: PMID:11292324 previously reported this variant to be associated with the infantile form of SD. Genomic DNA amplification, heteroduplex analysis, cloning and sequencing revealed a 4-bp deletion in exon 4 at position 178. The result is a frameshift mutation that leads to a stop codon in exon 5. This mutation is associated with a dramatic decrease of HEXB mRNA levels.

6 individuals noted to have this variant in homozygosity. This is the same as the MPS registry number of homozygotes and uses the registry, so will only be scoring for Clarke et al. paper

However, a glycosyltransferase assay using the wildtype EXTL3 and th eP318L variant showed reduced enzyme activity in the P318L variant compared to wildtype, and simiar levels of activity as untransfected/ mock controls. This indicates the P318L mutation acts as a loss of protein function of the enzyme activity.

All patients that were operated on between 1995 and 2010 in the University Medical Center Groningen from who frozen hemangioblastoma tissue was available in the tissue bank of the Department of Pathology were eligible. Through PCR (MSP) and MLPA, one patient sample was confirmed with a germline mutation (c.462A>C) in the VHL gene. The patients' manifestations was thus only stated as hemangioblastoma; No other phenotypic or demographic information was available. Note: This sample was likely duplicated in 24132471

A 39 year old man was confirmed to have a germline exon 1 deletion of the VHL gene at age 26. Details regarding genotyping methods are not specified. He presented with epistaxis at age 34 and CT scans showed an ethmoid mass later identified as a primary microcystic adenoma. He underwent endoscopic transsphenoidal resection of the legion and he was negative for metastatic disease. Analysis of tumour DNA showed it to be heterozygous for an intron 1 polymorphism (c.341-50G>A). He had a history of cerebellar haemangioblastoma and ccRCC.

gnomAD: N/A

VariantEvidence: The modified amino acids are located in a domain common to all pVHL isoforms, the highly conserved cctbinding domain of the protein, involved in the formation of the pVHL elongin complex that is crucial for tumor suppression. Furthermore, the mutant protein is prematurely truncated and lacks the C-terminal half of exon 2 and exon 3 completely, which includes the nuclear export signal and the elongin C binding site of pVHL. Thus, this truncated protein would affect the two functional isoforms of pVHL: the major isoform pVHL30 and pVHL19, but not isoform 2, which lacks exon 2 but is not functional

Between 1994 and 2001, the Dutch VHL working group conducted DNA analysis on 146 probands with VHL-associated manifestations. DNA of probands was extracted from peripheral blood samples. Exons 1, 2 and 3 of the VHL gene and their flanking untranslated and intronic coding sequences were amplified by PCR and subjected to semi-automated sequence analysis. Screening for structural rearrangements, including deletions, involving the VHL gene was performed by Southern blot analysis and the multiplex ligation-dependent probe amplification (MLPA) assay. Deletions encompassing the entire VHL gene were confirmed by FISH analysis on lymphocytes from affected individuals. VHL mutations were identified in 43 families. This splice mutation c.341-2A>C was found in a VHL patient with hemangioblastomas of the retina and central nervous system, renal cysts and RCC, and pancreatic cysts (family no. 32). They were described as being familial VHL however no other members were described. ACMG evidence codes: 'PSV1' because they observe a splice-site variant in a gene where loss-of-function is known mechanism of disease, 'PP4' because the patients' phenotypes or family history are highly specific for a disease with single genetic etiology.

Complete molecular analysis of the VHL gene on genomic DNA was conducted on 4 patients and some of their relatives. Peripheral blood lymphocytes were collected and the VHL gene dosage was evaluated by quantitative Southern blot or real-time quantitative PCR analysis. The coding region was studied via direct sequencing. One patient (4), a 16 year old female, was found to harbour a polymorphic variant on the 3' UTR of the VHL gene (c.*1149 A>G). This patient also harboured the promoter region mutation c.–65_–55dup11 of the VHL gene. She presented with an isolated retinal angioma and an unremarkable family history although the dup11 variant was inherited from an nonsymptomatic parent. ACMG evidence codes: 'PP4' since the patient presents phenotypes highly specific for a disease with a single genetic etiology.

This patient's great aunt (II-1) carried two different VHL mutations; the Ser80Asn and Pro25Leu but herself was asymptomatic. She passed the Ser80Asn mutation to her daughter, the proband (III-1), who had renal cell carcinoma, brain hemangioblastoma, and pheochromocytoma. Refer to figure 1 for pedigree.
