Ectodermal dysplasia, ectrodactyly, clefting, anophthalmia microphthalmia, and genitourinary anomalies: nosology of goltz-gorlin syndrome versus eec syndrome

We report on two unrelated Brazilian girls born to normal and nonconsanguineous parents and presenting ectodermal dysplasia, ectrodactyly, clefting, tear duct anomalies, and micro/anophthalmia. The clinical picture presented by these patients suggests the diagnosis of Goltz-Gorlin (Focal dermal hypoplasia) syndrome and EEC syndrome.

WORD-FINDING DIFFICULTIES, VERBAL PARAPHASIAS, AND VERBAL DYSPRAXIA IN 10 INDIVIDUALS WITH FRAGILE-X-SYNDROME

Speech/language disorders are common in the fragile X syndrome. [Howard-Peebles, 1979: Am J Hom Genet 31:214-222; Renier et al., 1983: J Ment Defic Res 27:51-59; Sparks, 1984: Birth Defects and Speech-Language Disorders, pp, 39-43; Hanson et al., 1986: Am J Med Genet 23:195-206]. Verbal paraphasias have been considered a rare feature and word-finding difficulties have seldom been reported. Here we report on ten Brazilian patients who were evaluated for speech/language disturbances and found that word-finding difficulties were present in 50% of the cases, which is a slightly higher frequency than that of clear dyspraxia. We suggest, therefore, that word-finding difficulties and verbal dyspraxia can be a common feature within the spectrum of this syndrome. Additional speech findings are discussed.

MICHELS SYNDROME IN A BRAZILIAN GIRL BORN TO CONSANGUINEOUS PARENTS

We report on a Brazilian girl born to consanguineous parents and presenting with craniosynostosis, telecanthus, blepharophimosis, blepharoptosis, epicanthus inversus, cleft lip and palate, skeletal defects, and hearing loss. This combination of anomalies appears to constitute the Michels syndrome. (C) 1995 Wiley-Liss, Inc.

MACROSOMIA, OBESITY, MACROCEPHALY AND OCULAR ABNORMALITIES (MOMO SYNDROME) IN 2 UNRELATED PATIENTS - DELINEATION OF A NEWLY RECOGNIZED OVERGROWTH SYNDROME

We describe 2 unrelated patients, a boy and a girl, with an overgrowth syndrome and the following common characteristics: macrocrania, obesity, ocular abnormalities (retinal coloboma and nystagmus), downward slant of palpebral fissures, mental retardation, and delayed bone maturation. Both cases are of sporadic occurrence with no consanguinity between the parents. We suggest that this syndrome is due to a new autosomal dominant mutation and propose to designate it with the acronym of ''MOMO syndrome'' (Macrosomia, Obesity, Macrocrania, Ocular anomalities).

NEWLY RECOGNIZED AUTOSOMAL RECESSIVE FACIOTHORACOSKELETAL SYNDROME

We report on 2 brothers, born to consanguineous parents presenting thin/long face, small ears, blepharophimosis, malar hypoplasia, long neck, pectus excavatum, brachy-camptodactyly, and sacral dimple. We suspect that these patients represent a previously undescribed autosomal recessive syndrome. (C) 1994 Wiley-Liss, Inc.

Ulnar ray a/hypoplasia: evidence for a developmental field defect on the basis of genetic heterogeneity. Report of three Brazilian families.

We report on five Brazilian patients from three unrelated families with congenital anomalies of the upper limbs. Ulnar aplasia/hypoplasia was the main reason for examining these patients. Evidence for existence of an ulnar developmental field is based on genetic heterogeneity. Clinical and genetic aspects of the ulnar ray defects are discussed.

FG syndrome in a Brazilian child with additional previously unreported signs.

We report on a Brazilian child with typical manifestations of the FG syndrome. Pigmentary dysplasia, metacarpal fusion and peculiar anatomopathological findings are additional undescribed signs.

Interstitial long-arm deletion of chromosome 7 and ectrodactyly

An interstitial deletion of 7q21 was found in a boy with mental retardation, microcephaly, convergent strabismus, micrognathia, genital anomalies, and other findings, including ectrodactyly.

Metacarpophalangeal pattern profile in Marfan syndrome and Marfan-like patients

Marfan syndrome (MFS) is an autosomal dominant trait due to mutations in the fibrillin gene (FBN1). The MFS expressivity is variable, and its diagnosis relies completely on clinical criteria. Atypical cases and Marfan- like (marfanoid) clinical presentations are commonly found. The metacarpophalangeal pattern profile (MCPP), a radiological method in which the 19 tubular hand bones are assessed, has been used in the diagnosis of various syndromes. To investigate whether the MCPP was adequate to discriminate between MFS and Marfan-like subjects, we studied 38 patients who were referred to our service because they had an MFS diagnosis, diagnostic hypothesis, or differential diagnosis or had arachnodactyly with dolichostenomelia. Two groups were formed: 1) MFS: 21 patients with a mean age of 18.3 (10.8 S.D.) years and 2) Marfan-like syndromes: 16 patients who did not meet the current criteria, with a mean age of 14.6 (4.6 S.D.) years. The MCPP was performed in each case following the classical technique, and a characteristic mean profile was obtained for group I (MFS), with Z scores ranging from 0.69 to 2.73 (1.80 ± 0.50; mean ± S.D.). In group I, three cases had no correlation with the typical MFS pattern. In group II, three cases had an MFS pattern. The correlation with the mean MCPP of MFS permitted the differential diagnosis of MFS and marfanoid syndromes with 86% sensitivity, 81% specificity, and 86% positive and 81% negative predictive values. The results suggest that MCPP can be used effectively as an auxiliary tool in the nosology of these conditions and, because there is no change in MCPP with age, can be helpful in early diagnosis.

Blepharocheilodontic (BCD) syndrome: Expanding the phenotype?

We describe affected individuals in three generations of a family and another sporadic case, all Brazilian patients, with a combination of signs that diagnose the BCD syndrome. In addition to the cardinal signs, the sporadic case has hypothyroidism and imperforate anus, which was observed previously in one patient. The broadened phenotype and the possibility of involvement of p63 and IRF6 genes in this condition are discussed. © 2003 Wiley-Liss, Inc.
