Molecular and phenotypic spectrum of cardio-facio-cutaneous syndrome in Chinese patients

Feng Biyun

Background: Cardio-facio-cutaneous (CFC) syndrome is a RASopathy subtype that presents with unique craniofacial dysmorphology, congenital heart disease, dermatologic abnormalities, growth retardation, and intellectual disability. This study describes the phenotypic spectrum of CFC in China and its association with CFC syndrome gene variants.Results: Twenty Chinese CFC patients, aged 0.6 to 9.5 years old, were included in...

A novel CEP57 mutation of mosaic variegated aneuploidy syndrome in a Chinese girl: a case report and review of literature

Feng Biyun , Zhang Qianwen , Wang Xiumin ,

Background: Mosaic variegated aneuploidy syndrome(MVA)is a rare genetic disease characterized by mosaic aneuploidies, intrauterine growth restriction, developmental delay, microcephaly, facial dysmorphism, mental retardation, and susceptibility to tumor. It is autosomal recessive and caused by mutations in BUB1B, CEP57, and TRIP13. This study hereby presents a 9-year-old girl with intrauterine growth restriction, short stature, microcephaly, faci...

Gao Shiyang , Zhang Qianwen , Feng Biyun , Gu Shili , Yao Ru-en , Yu Tingting , Ding Yu , Wang Xiumin

Background: Bardet Biedl syndrome(BBS) is a type of non-motile ciliopathy primarily characterized by retinal dystrophy, obesity, polydactyly, cognitive impairment, urogenital anomalies and renal abnormalities. To date, 26 genes have been reported to be associated with BBS: BBS1-BBS21, IFT74, SCLT1, SCAPER and NPHP1. BBS is genetically heterogeneous with significant clinical overlap with other ciliopathies, further c...

A novel heterozygous variant of FOXJ1 in a Chinese female with primary ciliary dyskinesia and hydrocephalus: A case report and literature review

Gao hiyang , Zhang Qianwen , Feng Biyun , Gu Shili , Li Zhiying , Sun Lianping , Yao Ru-en , Yu Tingting , Ding Yu , Wang Xiumin

Background: Primary ciliary dyskinesia (PCD) is a type of ciliary dyskinesia that is usually caused by autosomal recessive inheritance and can manifest as recurrent respiratory infections, bronchiectasis, infertility, laterality defects, and chronic otolaryngological disease. Although ependymal cilia, which affect the flow of cerebrospinal fluid in the central nervous system, have much in common with respiratory cilia in terms of structure and function, hydroc...
