Another possible sporadic case of the Ohdo blepharophimosis syndrome is described and compared with the seven patients previously reported. It can be considered a distinctive syndrome showing blepharophimosis, ptosis, dental hypoplasia, mental retardation and deafness. This case helps to define the spectrum of the phenotypic anomalies.

Two unrelated patients, aged 19 and 6 years, were studied and diagnosed as having Myhre syndrome (MS). This review, together with three previous cases, permits further delineation of MS. The main features are: short stature, mental retardation, blepharophimosis, muscular hypertrophy, decreased joint mobility, thick calvarium, broad ribs, hypoplastic iliac wings and short tubular bones. Advanced paternal age at the propositi's birth suggests an autosomal dominant mutation as the cause of MS.

Two unrelated Mexican girls, aged 14 months and 6 years respectively, with Kaufman oculocerebrofacial syndrome, are reported. Both showed psychomotor retardation, microcephaly, blepharophimosis and delayed growth as the main features; the infant also presented preauricular tags and large clitoris. Comparative analysis with previous cases reveals a heterogeneous syndrome in which the micro-brachycephaly, the mongoloid slanted eyes with different anomalies, the micrognathia and the neonatal respiratory distress are the most typical characteristics of this mental retardation syndrome.

Two additional cases of the Ohdo blepharophimosis syndrome are described and compared to the 5 patients previously reported. Blepharophimosis, ptosis, dental hypoplasia, mental retardation, and deafness can be considered as common manifestations of the syndrome. Male patients show cryptorchidism and scrotal hypoplasia.

Two cases are presented with a phenotype mostly resembling the condition named Marden-Walker syndrome. Main features of this condition are blepharophimosis, micrognatia, congenital joint contractures, mental retardation, growth retardation and decreased muscular mass. Follow-up data of patients with this condition are scarce and most patients reported so far were infants or young children. We report two patients meeting many of the criteria proposed for diagnosing this particular phenotype. One case was diagnosed in adolescence and the other as an adult. Initially described as a syndrome, this condition is more likely to be a phenotypic expression of various heterogeneous diseases.

Dubowitz syndrome is an autosomal recessive condition characterized by pre- and postnatal growth retardation, eczema, telecanthus, epicanthal folds, blepharophimosis, ptosis, and broadening of the bridge and tip of the nose. The initial patients described had varying degrees of mental retardation and there is little information about long-term developmental outcome. We present a boy with Dubowitz syndrome who does not have developmental delays, providing additional evidence that the phenotype includes normal neurodevelopmental status.

Partial trisomy 6p is regarded as a distinct phenotype with short stature, failure to thrive, facial dysmorphisms with blepharophimosis, mental retardation and other malformations. An 18-month-old girl with typical features of partial trisomy 6p showed a de novo unbalanced translocation resulting in partial trisomy 6p21 to pter and partial monosomy 18p11 to pter. The translocation was observed in all fibroblasts analyzed, but only in 6% of the peripheral lymphocytes.

We have evaluated a 3 2/12 year old girl who presented with unilateral blepharophimosis, ptosis of the eyelid, and mental retardation. Additional dysmorphic features include microcephaly, high, narrow forehead, short stubby fingers, and adduction of the right first toe. Cytogenetic analysis showed an unbalanced karyotype consisting of 46,XX,add(7)(q+) that was de novo in origin. Fluorescence in situ hybridisation (FISH) using microdissected library probe pools from chromosomes 1,2,3,7, and 3q26-qter showed that the additional material on 7q was derived from the distal end of the long arm of chromosome 3. Our results indicate that the patient had an unbalanced translocation, 46,XX,der(7)t(3;7)(q26-qter;q+) which resulted in trisomy for distal 3q. All currently reported cases of BPES (blepharophimosis-ptosis-epicanthus inversus syndrome) with associated cytogenetic abnormalities show interstitial deletions or balanced translocations involving 3q22-q23 or 3p25.3. Our patient shares similar features to BPES, except for the unilateral ptosis and absence of epicanthus inversus. It is possible that our patient has a contiguous gene defect including at least one locus for a type of blepharophimosis, further suggesting that multiple loci exist for eyelid development.

We report on 22 individuals referred for genetic evaluation because of blepharophimosis. Fourteen of these patients had the blepharophimosis syndrome: 5 familial and 9 sporadic. Mental retardation or developmental delay was seen in 8 of the 12 children in whom this could be assessed. Eight of 22 children had a malformation syndrome other than the blepharophimosis syndrome. All 8 of these children were mentally retarded or developmentally delayed. Two of these 8 had recognized disorders (branchio-oto-renal syndrome and a ring 4 chromosome); the remaining 6 had unrecognized malformation syndromes. Based on this information, it is suggested that children with blepharophimosis be evaluated carefully for underlying conditions and that they be observed for developmental disabilities because of the frequent association.

Ohdo blepharophimosis syndrome (OBS) is a multiple congenital anomalies-mental retardation syndrome composed of blepharophimosis, ptosis, dental hypoplasia, partial deafness, and mental retardation. Previously reported cases of OBS have been sporadic except for the report by Ohdo et al. [1986, J Med Genet 23:242-244] that described two affected sisters and a first cousin favoring autosomal recessive inheritance. The original report by Ohdo et al. [1986] may reflect nonpenetrance of an autosomal dominantly inherited disorder or genetic heterogeneity of OBS. We report on a child and the mother who have blepharophimosis, ptosis, dental anomalies, mild hearing loss, and mental retardation. Chromosome analysis in both showed a balanced paracentric inversion of the long arm of chromosome 9, which was also present in two phenotypically normal sibs of the mother. This is the first report of vertical transmission of OBS suggestive of autosomal dominant inheritance. X-linked dominant and mitochondrial inheritance are other possible modes of inheritance.
