FOXC2 disease-mutations identified in lymphedema-distichiasis patients cause both loss and gain of protein function
Dominant mutations in the FOXC2 gene cause a form of lymphedema primarily of the limbs that usually develops at or after puberty. In 90-95% of patients, lymphedema is accompanied by distichiasis. FOXC2 is a member of the forkhead/winged-helix family of transcription factors and plays essential roles in different developmental pathways and physiological processes. We previously described six unr...
متن کاملThe establishment of a predictive mutational model of the forkhead domain through the analyses of FOXC2 missense mutations identified in patients with hereditary lymphedema with distichiasis.
The FOX family of transcription factor genes is an evolutionary conserved, yet functionally diverse class of transcription factors that are important for regulation of energy homeostasis, development and oncogenesis. The proteins encoded by FOX genes are characterized by a conserved DNA-binding domain known as the forkhead domain (FHD). To date, disease-causing mutations have been identified in...
متن کاملClinical heterogeneity in lymphoedema-distichiasis with FOXC2 truncating mutations.
BACKGROUND Hereditary lymphoedema-distichiasis (LD) is an autosomal dominant disorder that classically presents as lymphoedema of the limbs, with variable age of onset, and extra aberrant growth of eyelashes from the Meibomian gland (distichiasis). Other major reported complications include cardiac defects, cleft palate, and extradural cysts. Photophobia, exotropia, ptosis, congenital ectropion...
متن کاملNovel FOXC2 Mutation in Hereditary Distichiasis Impairs DNA-Binding Activity and Transcriptional Activation
Distichiasis presents as double rows of eyelashes arising from aberrant differentiation of the meibomian glands of the eyelids, and it may be sporadic or hereditary. FOXC2 gene mutations in hereditary distichiasis are rarely reported. Here, we examined two generations of a Chinese family with hereditary distichiasis but without lymphedema or other features of LD syndrome. The FOXC2 gene was amp...
متن کاملTruncating mutations in FOXC2 cause multiple lymphedema syndromes.
Hereditary lymphedemas are developmental disorders of the lymphatics resulting in edema of the extremities due to altered lymphatic flow. One such disorder, the lymphedema-distichiasis syndrome, has been reported to be caused by mutations in the forkhead transcription factor, FOXC2. We sequenced the FOXC2 gene in 86 lymphedema families to identify mutations. Eleven families were identified with...
