Comment on mode of inheritance: Although not yet listed in DD-Gene2Phenotype, PKD1 is listed in OMIM with AD inheritance for Polycystic kidney disease 1, 173900. Monoallelic MOI was also listed in the original PAGE Additional gene list. However the external review and the two cited papers support both AD and AR inheritance for polycystic kidney disease (PKD). PMID:23624871 note that recessive polycystic kidney disease (ARPKD) frequently presents antenatally or in the neonatal period with severe renal involvement.Created: 4 Jun 2019, 3:48 p.m.
PMID:23624871 (Gilbert et al., 2013) was added as a publication by Julia Baptista. The authors describe a male fetus with renal enlargement and oligohydramnios diagnosed at 27 weeks of gestation. This presentation resembled autosomal recessive PKD (ARPKD). Genetic analysis revealed a heterozygous truncating variant (p.Ser2788fs) in PKD1 inherited from the mother, and three unreported PKD1 variants inherited from the father. Although the authors don't exclude the possibility of a pathogenic variant in an additional gene, the paternally-inherited alleles support biallelic PKD1 alleles causing the fetal kidney anomalies.Created: 4 Jun 2019, 3:47 p.m.
PMID:20558538 (Vujic et al., 2010) was added as a publication by Julia Baptista. The authors describe two pedigrees each with two patients with onset of polycystic kidney disease in-utero. Mutation analysis suggested that both families inherited, in trans, two incompletely penetrant PKD1 alleles, thus supporting autosomal recessive PKD.Created: 4 Jun 2019, 3:46 p.m.
Comment on mode of inheritance: Updated the MOI from monoallelic to monoallelic AND biallelic, to match the review of Julia Baptista and evidence provided in PMID:20558538 (Vujic et al., 2010) and PMID:23624871 (Gilbert et al., 2013).Created: 4 Jun 2019, 3:45 p.m.
This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as a Green gene.Created: 24 Mar 2019, 4:30 p.m.
Disease confidence rating in PAGE Additional gene list: Confirmed. Mode of inheritance in PAGE list: monoallelic. Mode of pathogenicity in PAGE list: loss of function.Created: 11 Dec 2018, 9:05 a.m.
Mode of inheritance for gene: PKD1 was changed from BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal to BOTH monoallelic and biallelic (but BIALLELIC mutations cause a more SEVERE disease form), autosomal or pseudoautosomal
