Aortopathy_Connective Tissue Disorders
Gene: GORAB
13 families described with biallelic LoF variants (PMID: 18997784). Phenotypes included wrinkly skin and osteoporosis.
One more individual described with a homozygous missense variant (PMID: 19681135). Clinical diagnosis of GO was based on the presence of typical facial features, reduced skin elasticity, and decreased bone density.
There have been no clinical reports since 2009.
This gene is Green in PanelApp England EDS panel because it has phenotypic overlap with Eherls Danlos syndrome. I have left it amber as I'm not sure if the overlap is sufficient for this panel.
From OMIM: "Geroderma osteodysplasticum (GO) is an autosomal recessive disorder characterized by skin wrinkling limited to the dorsa of hands and feet and to the abdomen, bowed long bones, and osteopenia with frequent fractures. There is a distinctive facial appearance with droopy skin at the cheeks, maxillary hypoplasia, and large ears. Adult patients appear prematurely aged"
