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 affects an acceptor splice site in intron 13 of the PROM1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PROM1 are known to be pathogenic (PMID: 17605048, 19718270, 24154662, 25474345). This variant is present in population databases (rs372513650, gnomAD 0.007%). Disruption of this splice site has been observed in individuals with clinical features of autosomal recessive PROM1-related retinal dystrophy (PMID: 28041643). ClinVar contains an entry for this variant (Variation ID: 236527). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
