To date, 11 HPS types have been reported (HPS-1 to HPS-11), each defined by disease-causing variants in specific genes. Variants in the <jats:italic>HPS1<\/jats:italic> gene were found in approximately 15% of HPS patients, most of whom harbor the Puerto Rican founder mutation. In this study, we report six affected individuals from three nonconsanguineous families of Ashkenazi Jewish descent, who presented with OCA and multiple ecchymoses and had normal platelet number and size. Linkage analysis indicated complete segregation to <jats:italic>HPS3<\/jats:italic>. Sequencing of the whole coding region and the intron boundaries of <jats:italic>HPS3<\/jats:italic> revealed a heterozygous c.1163+1G&amp;gt;A variant in all six patients. Long-range PCR amplification revealed that all affected individuals also carry a 14,761bp deletion that includes the 5\u2032UTR and exon 1 of <jats:italic>HPS3<\/jats:italic>, encompassing regions with long interspersed nuclear elements. The frequency of the c.1163+1G&amp;gt;A splice site variant was found to be 1:200 in the Ashkenazi Jewish population, whereas the large deletion was not detected in 300 Ashkenazi Jewish controls. These results present a novel <jats:italic>HPS3<\/jats:italic> deletion mutation and suggest that the prevalence of HPS-3 in Ashkenazi Jews is more common than previously thought.<\/jats:p>","DOI":"10.3389\/fgene.2022.936064","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T05:31:45Z","timestamp":1660541505000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Oculocutaneous albinism and bleeding diathesis due to a novel deletion in the HPS3 gene"],"prefix":"10.3389","volume":"13","author":[{"given":"Dina","family":"Marek-Yagel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shachar","family":"Abudi-Sinreich","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"Macarov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alvit","family":"Veber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nechama","family":"Shalva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amit Mary","family":"Philosoph","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben","family":"Pode-Shakked","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"May Christine V.","family":"Malicdan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yair","family":"Anikster","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,8,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"376","DOI":"10.1038\/ng576","article-title":"Mutation of a new gene causes a unique form of Hermansky-Pudlak syndrome in a genetic isolate of central Puerto Rico","volume":"28","author":"Anikster","year":"2001","journal-title":"Nat.
