| Popis: | Kenny-Caffey syndrome (KCS) type 2 (OMIM 127000) is a rare syndromic cause of hypoparathyroidism which is characterized by proportionate short stature, long bone abnormalities, delayed closure of anterior fontanelle, eye abnormalities, and normal intelligence. It is caused by variants in FAM111A (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 years follow-up. 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-dependent 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-orchidism, 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. |
