Mainzer – Saldino syndrome or Cono – renal syndrome describes the association of cone shaped phalangeal epiphyses and nephronophthisis. In some patients retinitis pigmentosa, ataxia and hepatic fibrosis have been described. Underlying gene mutations have been found in genes responsible for the intraflagellar transport in primary cilia. This syndrome is inherited in an autosomal – recessive manner and belongs together with Jeune asphyxiating thoracic dysplasia, Ellis van Creveld and Sensenbrenner syndrome to the group of short rib polydactyly syndromes (short rib thoracic dysplasia with or without polydactyly)
