Comment on list classification: Keeping red. Genomics England clinical team note this is not a particularly limb-predominant phenotype, and is better suited to the skeletal dysplasia/Stickler syndrome panels.

Associated with Joint laxity, short stature, and myopia (#617662) in OMIM and Larsen syndrome (probable) in Gene2Phenotype.

PMID: 28475863 - Patel et al 2017 - 2 cases. Family 1 - a multiplex consanguineous Saudi family affected by severe and recurrent large joint dislocation and severe myopia. The index patient also had severe kyphoscoliosis. Both the index patient and her brother had short stature and bilateral talipes equinovarus deformity. A homozygous truncating variant in GZF1 was identified (c.865G>T (pGlu289∗). Family 2 - another multiplex consanguineous Saudi family affected by severe myopia, retinal detachment, and milder skeletal involvement (generalized joint laxity). 1 family member had bilateral talipes. A second homozygous truncating GZF1 variant was identified (c.1054dup (p.Thr352Asnfs∗50). Neither variant was present in 2,379 Saudi exomes or the Exome Aggregation Consortium (ExAC) Browser. In functional studies they found using immunofluorescence, strong localization of GZF1 in the developing mouse eye and, to a lesser extent, in the mesenchyme of the developing mouse limb buds. Using 3 patient-derived lymphoblastoid cell lines they found 1,095 genes to be dysregulated in affected individuals.
