Genes affected
FLVCR1 (HGNC:24682): (FLVCR choline and heme transporter 1) This gene encodes a member of the major facilitator superfamily of transporter proteins. The encoded protein is a heme transporter that may play a critical role in erythropoiesis by protecting developing erythroid cells from heme toxicity. This gene may play a role in posterior column ataxia with retinitis pigmentosa and the hematological disorder Diamond-Blackfan syndrome. [provided by RefSeq, Jan 2011]
FLVCR1 Gene-Disease associations (from GenCC):
  • FLVCR1-related retinopathy with or without ataxia
    Inheritance: AR Classification: DEFINITIVE Submitted by: ClinGen
  • posterior column ataxia-retinitis pigmentosa syndrome
    Inheritance: AR Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Illumina, G2P, Orphanet
