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]

This sequence change creates a premature translational stop signal (p.Leu386*) 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). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with retinal dystrophy and cone-rod dystrophy (PMID: 23591405, 24474277). ClinVar contains an entry for this variant (Variation ID: 253326). For these reasons, this variant has been classified as Pathogenic. -
