The condition has an incidence of approximately one per two million people worldwide. There is no known single effective treatment available for FOP. We report the world\u2019s first case of a healthy infant born following in vitro fertilisation (IVF) and preimplantation genetic testing for monogenic disorder (PGT-M) using Karyomapping for FOP.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>A 30-year-old Caucasian female with FOP presented with her partner seeking IVF with PGT-M to achieve a healthy pregnancy with an embryo unaffected by FOP.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The couple underwent IVF and PGT-M using Karyomapping as the testing method.

This was subsequently weaned down with reducing doses every two days. The patient underwent uncomplicated oocyte retrieval, yielding 12 mature oocytes. Following intracytoplasmic sperm injection (ICSI), ten zygotes having two pro-nuclei were cultured, and six underwent trophoectoderm biopsy and vitrification 5\u20136\u00a0days after retrieval. PGT-M via Karyomapping revealed four out of six (66.7%) of blastocysts were not carriers of the maternal high-risk FOP allele. In total, the patient had three separate embryo transfers. Pregnancy was achieved following the third frozen embryo transfer, which went to 37\u00a0weeks\u2019 gestation, and delivered by Caesarean section. The baby was born in excellent condition and is unaffected by FOP.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>IVF\/ICSI and PGT-M using Karyomapping was successfully implemented to identify embryos carrying the high-risk FOP allele resulting in a healthy livebirth.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s13256-024-04504-4","type":"journal-article","created":{"date-parts":[[2024,4,26]],"date-time":"2024-04-26T00:01:49Z","timestamp":1714089709000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Successful preimplantation genetic testing for fibrodysplasia ossificans progressiva: a case report"],"prefix":"10.1186","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8852-0892","authenticated-orcid":false,"given":"Sughashini","family":"Murugesu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin P.","family":"Jones","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Serhal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jara","family":"Ben-Nagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,4,26]]},"reference":[{"issue":"6","key":"4504_CR1","doi-asserted-by":"publisher","first-page":"756","DOI":"10.1242\/dmm.010280","volume":"5","author":"FS Kaplan","year":"2012","unstructured":"Kaplan FS, Chakkalakal SA, Shore EM.
