Fetal anomalies
Gene: GNASComment on mode of inheritance: Disease causing variants in the GNAS locus have differing expression panels. Pseudohypothyroidism Ia, Ib & Ic are all caused by GNAS variants arising in the maternal alleles, therefore, the mode of inheritance (MOI) for GNAS in these conditions should be monoallelic maternally imprinted. Pseudopseudohypoparathyroidism, OMIM:612463 and Osseous heteroplasia, progressive, OMIM:166350 are associated with variants in the paternal alleles therefore, the mode of inheritance for GNAS in these conditions should be monoallelic paternally imprinted. Because the Fetal anomalies panel is representing various phenotypes, the MOI has been set to monoallelic, imprinted status unknown.Created: 13 Oct 2022, 2:13 p.m. | Last Modified: 13 Oct 2022, 2:13 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.
