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 testingLabcorp Genetics (formerly Invitae), LabcorpJun 20, 2022For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 438213). This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 28041643, 32581362). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Tyr570*) in the PROM1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PROM1 are known to be pathogenic (PMID: 17605048, 19718270, 24154662, 25474345). -
