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] CIViC Summary for PROM1 Gene
Forensic Context
A study in humans analyzing heart tissue samples from patients with various structural heart diseases identified the PROM1 as a gene expression marker that is significantly up-regulated in diseased samples compared to controls, with a mean fold change of 1.8225 and an adjusted p-value of 6.1354 × 10^-18 [Fajarda et al.
