METHODS: Ten family members from three generations participated in this study and received the thorough ophthalmologic examination. Focused exome sequencing on a proband was performed to confirm the target mutations (MYOC c.1021T&gt;C) in the family members, and the direct sequencing was conducted. Variant was analyzed according to the American College of Medical Genetics and Genomics and the Association for Molecular Pathology (ACMG\/AMP) guidelines.  RESULTS: A nucleotide change from thymine to cytosine at c.1021T&gt;C was found in eight family members. Three members diagnosed with primary open angle glaucoma (POAG) were characterized by severe clinical presentations, high intraocular pressure, and poor response to medical treatment (100% of the patient required filtering surgery). On variant analysis by ACMG\/AMP guidelines, Ser341Pro is not found in normal population. Multiple computational predictive programs support a deleterious effect of Ser341Pro variant (PolyPhen 2, SIFT, Mutation Taster). Ser341Pro could be involved in moderate (PM) and supporting (PP) criteria (PM1, PM2, PP2, PP3). Combining the criteria, Ser341Pro has a combination of 2 moderate (PM1+PM2) and 2 supporting (PP2+PP3) criteria, which is interpreted to \u201clikely pathogenic\u201d. CONCLUSION: The Ser341Pro variant is correlated with severe phenotype of POAG. There are similar clinical aspects to previous studies: autosomal dominant inheritance, incomplete penetrance (62.50% and 66.67%), and proportion of patients requiring trabeculectomy (100% in both study). According to ACMG\/AMP guidelines and the previous basic researches, the Ser341Pro variant had a \u201cstrong evidence of pathogenicity (PS3)\u201d and then it could be interpreted to \u201cpathogenic (PS3, PM1, PM2, PP2, PP3)\u201d. Additionally, Ser341Pro variant can be reported as \u201cc.1021T&gt;C (p.Ser341Pro), likely pathogenic, POAG, autosomal dominant\u201d according to guideline.<\/jats:p>","DOI":"10.18240\/ijo.2020.11.02","type":"journal-article","created":{"date-parts":[[2020,10,23]],"date-time":"2020-10-23T03:40:25Z","timestamp":1603424425000},"page":"1689-1696","source":"Crossref","is-referenced-by-count":5,"title":["Clinical and genetic analysis of Ser341Pro MYOC variant in a Korean family with primary open angle glaucoma"],"prefix":"10.18240","volume":"13","author":[{"name":"Department of Ophthalmology, Pusan National University College of Medicine, Busan 49241, Republic of Korea","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangwoo","family":"Moon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Namhee","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Laboratory Medicine, Dong A University College of Medicine, Busan 49201, Republic of Korea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiwoong","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Ophthalmology, Pusan National University College of Medicine, Busan 49241, Republic of Korea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"http:\/\/ies.ijo.cn\/en_publish\/2020\/11\/20201102.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,10,27]],"date-time":"2020-10-27T01:34:14Z","timestamp":1603762454000},"score":1,"resource":{"primary":{"URL":"http:\/\/ies.ijo.cn\/gjyken\/ch\/reader\/view_abstract.aspx?file_no=20201102&flag=1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,11,18]]},"references-count":0,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2020,11,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2020.11.02","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,11,18]]}}}
