Monoallelic EFEMP1 variants have been associated with Doyne honeycomb degeneration of retina (OMIM:126600). PMIDs 31792352; 32006683; 33807164 report four recessive EFEMP1 variants in three cases with a pronounced connective tissue disorder. PMID: 31792352 also describes a Efemp1 knockout mouse model, with a phenotype that matches the human cases.Created: 12 Feb 2024, 2:53 p.m. | Last Modified: 12 Feb 2024, 2:53 p.m.

Monoallelic variants in this gene are associated with a retinal dystrophy. New publications linking bi-allelic variants to a connective tissue disease phenotype:
PMID 31792352 reports one individual with a pronounced connective tissue phenotype presenting multiple and recurrent abdominal and thoracic herniae, myopia, hypermobile joints, scoliosis, and thin translucent skin. This individual has no clinical signs of retinal dystrophy.
PMID 32006683 reports 2 homozygous siblings (consanguinous) with multiple and recurrent herniae, pelvic and rectal prolapse, huge diverticula, marfanoid habitus, joint laxity, dorsal scoliosis, advanced bone age, pectus excavatum, dysmorphic facial features, and myopia.
Both papers mention that studies on EFEMP1−/− mice revealed a phenotypic resemblance.
