Medical Eponyms
Hansen-Larsen-Berg syndrome (1976)

Syndrome of total color blindness secondary to progressive cone dystrophy; degenerative liver disease; and endocrine dysfunction (hypothyroidism, ‘maturity-onset diabetes of the young’, repeated abortions or infertility). [aka Retinohepatoendocrinologic syndrome; OMIM 268040]

In 1972, Larsen and Egill Hansen had patients present with an unusual constellation of symptoms at the same time and were both working at Rikshospitalet. In 1976 Larsen, Hansen and Kåre Berg described this new syndrome found in 6 females in 2 sibships from a foresting community in eastern Norway with a high degree of consanguinity, and a male from another family. In then first paper they described the ophthalmological findings of progressive cone dystrophy. The fundi showed attenuated retinal vessels, disc pallor, and a generalized atrophic appearance without pigmentation. Photopic function was lost; scotopic function was well preserved. Creatine phosphokinase was elevated in the blood of all patients

Two further publications in 1978 described the Clinical and metabolic findings as well as the genetic studies.

Six females from two sibships in a family with a high degree of consanguinity and a male from another family are described: all have a new syndrome of total colour blindness (progressive cone dystrophy), liver degeneration and endocrine dysfunction.

The patients showed endocrine defects at different levels of regulation. None of the patients had children; two were probably infertile and three had had repeated abortions. Two patients had primary hypothyroidism and another two had low normal thyroid function with protracted thyrotropin-releasing hormone (TRH) test response, indicating a hypothalamic disorder…Diabetes mellitus of the “maturity-onset type of diabetes of the young” was observed in three patients, and a fourth had a borderline glucose tolerance with further impairment during pregnancy…Four of the patients had liver degeneration, demonstrated by elevated transaminases and unspecific parenchymal degeneration, fatty infiltration and isolated liver cell necrosis in the biopsy. All the patients, except the youngest, had progressive hearing loss, classified in four cases as neurogenous and probably cochlear…Elevated creatine phosphokinase was also observed. All the different lesions suggest a systemic disorder, possibly a membrane defect.
