Genes affected
PROM1 (HGNC:9454): (prominin 1) This gene encodes a pentaspan transmembrane glycoprotein. The protein localizes to membrane protrusions and is often expressed on adult stem cells, where it is thought to function in maintaining stem cell properties by suppressing differentiation. Mutations in this gene have been shown to result in retinitis pigmentosa and Stargardt disease. Expression of this gene is also associated with several types of cancer. This gene is expressed from at least five alternative promoters that are expressed in a tissue-dependent manner. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

Pathogenic, criteria provided, single submitterclinical testingInvitaeSep 13, 2022For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 425332). This variant has been observed in individual(s) with autosomal recessive retinitis pigmentosa (PMID: 24265693, 30576320; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs777497868, gnomAD 0.004%). This variant, c.1209_1229del, is a complex sequence change that results in the deletion of 8 and insertion of 1 amino acid(s) in the PROM1 protein (p.Gln403_Ser410delinsHis). -
