Split hand/split foot anomaly in a family segregating a balanced translocation with breakpoint on 7q22.1.

An apparently balanced translocation, t(2;7)(q21.1;q22.1) was detected in a female patient with bilateral split hand and right split foot. Split hand/split foot (SHSF) segregated as an autosomal dominant character with low penetrance in her family. The translocation was present in 6 of 13 additional relatives investigated, one of whom also had split hand on right. This observation provides further confirmation of the presence of a locus for SHSF on 7q and narrows the critical region to band 7q22.1. Defects caused by alterations of this chromosome region are variable and include manifestations of both syndromal and non-syndromal SHSF. Review of SHSF cases associated with chromosome 7 abnormalities showed a preferential involvement of the lower limbs and of the right side, suggesting the action of locally restricted developmental resistance mechanisms.

Possible new type of oral-facial-digital syndrome with retinal abnormalities: OFDS type (VIII)

The most recent classification of the oral-facial-digital syndromes (OFDS) includes 7 types distinguishable by different clinical signs. We describe 2 brothers presenting oral, facial, and digital anomalies and an additional manifestation consisting of specific retinal abnormalities, i.e., retinochoroideal lacunae of colobomatous origin. Our patients may be affected with a new type of OFDS, i.e., OFDS type VIII, characterized by eye abnormalities in addition to other manifestations that partially overlap with those of OFDS type II. Given that there are 2 affected brothers, we cannot distinguish between autosomal and X-linked recessive inheritance.

Autonomously functioning thyroid adenoma in a seven year old boy.

Hyperfunctioning thyroid adenoma is an extremely rare disorder in childhood. A case of a seven year old boy is reported. Clinical and laboratory findings were similar to those seen in adults. Recovery of thyroid function was prompt after ablative surgery and no substitutive therapy was required.

Facial midline defect in the fetal alcohol syndrome: embryogenetic considerations in two clinical cases.

We report on two unrelated patients with fetal alcohol syndrome with hypoplasia of the periocular region, resulting in a low and narrow forehead and hypotelorism. Other typical manifestations of the syndrome involving the facial midline are also present. These observations can be added to clinical and experimental evidence from other authors, supporting the concept that the facial anomalies of the fetal alcohol syndrome are the expression of a midline defect originating from the disruption of the ordered development of midline mesoderm cells during early embryogenesis.

IVIC syndrome: report of a second family.

The IVIC syndrome derives its name from the Instituto Venezolano de Investigaciones Cientìficas, where it was described by Arias et al. [Am J Med Genet 6:25-59, 1980]. We report on several individuals in a family with the IVIC syndrome, the second described in the literature. In this family there are 3 affected individuals in 2 generations. This observation shows that the IVIC syndrome is not a private syndrome, and confirms that it is due to an autosomal dominant mutation.

A dermatoglyphic study of a group of Sicilian children with fragile-X syndrome.

In a dermatoglyphic study of 14 fra(X) boys (compared with a control group of 191 normal schoolboys), we observed the following statistically significant (p less than 0.01) differences: 1) lower frequency of ulnar loops on the fingertips, particularly on the 2nd and 3rd fingers, with a corresponding increase of whorls; 2) transverse course of main line A; 3) increased frequency of abnormal palmar creases. The log score index of Simpson et al [1984] identified 71.4% of our patients and that of Rodewald et al [1986] 64.2%. The different values of these indexes can probably be attributed to ethnic differences. We think that by combining the results of dermatoglyphic analysis from several centers a more discriminatory log score index can be obtained.
