Familial occurrence of Summitt syndrome or a variant example of Carpenter syndrome?

In this report, we describe three sibs presenting an identical malformation syndrome i.e.: acrocephaly, brachydactyly, prominent metopic ridge, broad depressed nasal bridge, narrow maxillae, obesity and normal intelligence. We discuss the relationship between this combination of clinical signs and symptoms most compatible with the diagnosis of Summitt syndrome and the Carpenter syndrome.     

Familial occurrence of 18q-

Summary An unusual segregation of the partial long arm deletion of a chromosome 18 is reported. This aberration was found in the feeble-minded mother and in her 4 daughters. The fifth child has XXY-Klinefelter's syndrome. The carriers of 18q — in this family reveal small stature, microcephaly, and mental deficiency in the range from feeble-minded to severe imbecility. Other characteristic features commonly found in patients with 18q — syndrome, as mid-face retraction, downward slanting mouth, heart defect, and atretic ear canals were not observed.     

Familial occurrence of severe ulnar aplasia and lobster claw feet: A new syndrome

Summary In this paper we describe a previously unreported association of ulnar defect and lobster-claw deformity of the feet, occurring in four males belonging to two generations of the same family. Minor expression of the same ulnar reduction defect in female relatives suggests X-linked recessive inheritance, but an autosomal dominant with irregular expression cannot be excluded.Aspirant N.F.W.O.     

Familial occurrence of Glanzmann thrombasthenia]

Glanzmann's thrombasthenia, known also as Glanzmann's disease, is an autosomally inherited hemorrhagic disease with unique abnormalities of platelet functions. Authors present a large family in which Glanzmann's disease was diagnosed in the father and two sons. An analysis of platelet membranes enabled diagnosis of Glanzmann's thrombasthenia type II. A decrease in clot contractibility, fibrinogen binding to blood platelets, and decreased glycoprotein IIb and IIIa levels with marked impairment of GP IIb and IIIa complexes formation were characteristic for affected family members. One daughter died 8 days after birth with the symptoms of hemorrhagic diathesis. Mother and remaining three sons are healthy without the signs of Glanzmann's disease.     

Familial studies on the occurrence of natural autoantibodies

Natural autoantibodies are often incidentally found in healthy individuals who are not first-degree relatives of known patients with autoimmune diseases. In an attempt to examine whether there exists a familial tendency in the production of such natural autoantibodies, 134 healthy members of 32 families were examined for antibodies against ss-DNA, ds-DNA, poly (I), poly (G), cardiolipin, histones, Sm, RNP, SS-A (Ro) and SS-B (La), using an enzyme-linked immunosorbent assay. Only 16 of the 134 subjects (11.9%) were found to possess autoantibodies in their sera in a titer exceeding the mean by 3 SD, and none of the 'positive' subjects were related. We conclude that in contrast to the familial occurrence of the autoantibodies of first-degree relatives of patients with autoimmune disease, there is no familial tendency in the occurrence of natural autoantibodies.     

Familial occurrence of unilateral biphalangeal duplication of the thumb.

Duplication of the thumb is not an uncommon condition and the biphalangeal type is considered to be a sporadic event. We report the familial occurrence of a unilateral thumb polydactyly type 4 of Wassel (12) or preaxial polydactyly type 1 of Temtamy (11).
