PIKFYVE: A likely pathogenic missense mutation in the gene for phosphoinositide kinase, FYVE-type zinc finger containing (PIKFYVE) on chromosome 2q has been found in a 4-generation Chinese Korean family with autosomal dominant cataract (nuclear pulverulent, sutural, cortical punctate) cataract—in the absence of fleck corneal dystrophy [155]. The gene discussed is PIKFYVE; the disease is fleck corneal dystrophy.
