Despite BRCA1 biallelic pathogenic mutations being extremely rare, they have been reported to be embryonically lethal or to cause Fanconi anemia (FA). Here we describe a patient who was a 48-year-old female identified with biallelic pathogenic mutations of the BRCA1 gene, with no or very subtle FA-features. She was diagnosed with ovarian cancer and breast cancer at the ages of 43 and 44 and had a strong family history of breast and gynecological cancers.<\/jats:p>","DOI":"10.3390\/ijms22020889","type":"journal-article","created":{"date-parts":[[2021,1,18]],"date-time":"2021-01-18T05:17:34Z","timestamp":1610947054000},"page":"889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Case Report of Germline Compound Heterozygous Mutations in the BRCA1 Gene of an Ovarian and Breast Cancer Patient"],"prefix":"10.3390","volume":"22","author":[{"given":"Ava","family":"Kwong","sequence":"first","affiliation":[{"name":"Department of Surgery, The University of Hong Kong and University of Hong Kong-Shenzhen Hospital, Hong Kong, China"},{"name":"Department of Surgery, Hong Kong Sanatorium &amp; Hospital, Hong Kong, China"},{"name":"Hong Kong Hereditary Breast Cancer Family Registry, Hong Kong, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia Y.
