It is caused by variants in <jats:italic>FAM111A<\/jats:italic> (NM_001942519.1). In this review, we reported the first Chinese patients, a pair of monozygotic twins, with genetically confirmed KCS type 2 with over 20\u2009years follow\u2010up. We summarized the clinical features of 14 previously reported and genetically confirmed KCS type 2 patients; our twin patients exhibited a unique spinal manifestation which could be an important age\u2010dependent feature of KCS type 2. In this review, over 60% KCS type 2 patients had dental problem and over 80% suffered from refractive errors or structural eye abnormalities. Therefore, early dental, ophthalmological, and orthopedic assessments are warranted for KCS type 2 patients. Micro\u2010orchidism, previously reported in KCS type 2 patients, was also detected in our patients. The possibility of subfertility should be considered in male KCS type 2 patients. A multidisciplinary management approach for this rare syndrome is recommended.<\/jats:p>","DOI":"10.1002\/ajmg.a.61991","type":"journal-article","created":{"date-parts":[[2020,12,2]],"date-time":"2020-12-02T07:20:01Z","timestamp":1606893601000},"page":"636-646","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Adult Chinese twins with <scp>Kenny\u2013Caffey<\/scp> syndrome type 2: A potential age\u2010dependent phenotype and review of literature"],"prefix":"10.1002","volume":"185","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9923-7424","authenticated-orcid":false,"given":"Shirley S.
