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.
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.
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.
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.
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.
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.
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.
DA5D is characterized by ocular involvement usually in the form of ptosis and incomitant strabismus, but extraocular manifestations have also been reported.
DA type 5D (DA5D) is a rare, autosomal-recessive DA previously defined by us and is characterized by congenital contractures of the hands and feet, along with distinctive facial features, including ptosis.
Although the incidental association of OT and C10orf2 TWINKLE mutation is possible, the simultaneous onset of OT and eyelid ptosis at a much younger age than usually observed for OT raises the possibility of mitochondrial dysfunction and loss of mitochondrial DNA integrity in the pathogenesis of OT.
Autosomal dominant progressive external ophthalmoplegia due to the p.R357PPEO1 mutation is a late-onset ocular myopathy beginning with ptosis and progressing slowly.
Subjects with CFEOM3 frequently had asymmetrical blepharoptosis, limited vertical duction, variable ophthalmoplegia, exotropia, and paradoxical abduction in infraduction.
Four unrelated participants, also not meeting MDC, had large-angle exotropia, vertical gaze deficiency, and ptosis consistent with congenital fibrosis of the extraocular muscles type 3 (CFEOM3); 1 patient harbored a novel TUBB3 mutation, and 3 patients harbored previously reported de novo TUBB3 mutations.
Classical SCS associated with a TWIST 1 mutation could be separated phenotypically from the Muenke phenotype on the basis of the following features: low-set frontal hairline, gross ptosis of eyelids, subnormal ear length, dilated parietal foramina, interdigital webbing, and hallux valgus or broad great toe with bifid distal phalanx.
