ACTB and ACTG1 mutations have recently been reported to cause Baraitser-Winter syndrome (BRWS) - a rare condition characterized by ptosis, colobomata, neuronal migration disorder, distinct facial anomalies and intellectual disability.
Clinical characterization and identification of five novel FOXL2 pathogenic variants in a cohort of 12 Mexican subjects with the syndrome of blepharophimosis-ptosis-epicanthus inversus.
Germline mutations of the fork-head transcriptional factor forkhead box L2 (FOXL2) predispose embryos to autosomal-dominant blepharophimosis-ptosis-epicanthus inversus syndrome with primary ovarian insufficiency in female patients, but the mechanisms of FOXL2 in ovarian follicular development remain elusive.
Premature ovarian failure in the autosomal dominant disorder blepharophimosis-ptosis-epicanthus inversus is due to mutations in the gene encoding Forkhead L2 (FOXL2), producing putative truncated proteins.
Identification of a novel mutation in FOXL2 gene that leads to blepharophimosis ptosis epicanthus inversus and telecanthus syndrome in a Tunisian consanguineous family.
Mutations of FoxL2 are associated with the blepharophimosis/ptosis/epicanthus inversus syndrome characterized with craniofacial defects and premature ovarian failure.
We conclude that the FOXL2 mutation 904_939dup36 may account not only for blepharophimosis and ptosis but also for ovarian dysfunction and growth of the large corpus luteum cyst.
Ophthalmic findings were present in 3 of the 4 siblings with ECEL1-related distal arthrogryposis: bilateral ptosis with bilateral congenital fibrosis of the extraocular muscles, right ptosis with ipsilateral Y exotropia (exotropia increasing in upgaze), and right ptosis with ipsilateral Duane retraction syndrome.
