Rebecca Foulger (Genomics England curator)

Comment on list classification: Updated rating from Amber to Green based on two Green reviews from Penny Clouston and Zornitza Stark. Sufficient cases in the literature to support inclusion on the Ciliopathy panel, including two cases of short-rib thoracic dysplasia with polydactyly from PMID:28400947. Plus confirmed rating in DDG2P for CRANIOECTODERMAL DYSPLASIA TYPE 3; CED3 (also known as Sensenbrenner syndrome) is a rare autosomal recessive heterogeneous ciliopathy. Plus functional role with IFT43 involved in ciliary transport.

Transferring existing information over from Publications field: PMID:26892345 - a case report of a girl with mild intellectual disability, skeletal anomalies, congenital heart defect, myopia, and facial dysmorphisms identified a 4q24.2q24.3 microdeletion containing the IFT43 gene could provide some additional evidence: "immunocytochemistry showed increased accumulation of IFT-B proteins at the ciliary tip in patient-derived fibroblasts compared to control cells, demonstrating defective retrograde ciliary transport. This could suggest a ciliary defect in the pathogenesis of this disorder."
