Central pulverulent (Coppock) cataracts. A sibship of two Arab females with full-cousin normal parents.

Two Arab (Saudi) sisters are described each with bilateral typical central pulverulent (powdery) or Coppock cataracts. As their unaffected parents are first cousins, the heredity is probably autosomal recessive, unlike the autosomal dominant heredity of the vast majority of previously described cases in the literature. Chromosomes were normal in all four individuals. There are no other children in the family. Both children and both parents were phenotypically Fy a - b+, reasonably common in Arab populations, so that any linkage to the Duffy blood group is neither supported nor refuted.

A syndrome of multiple fundal anomalies in siblings with microcephaly without mental retardation.

Chorioretinal and retinal anomalies, among others, have been described in association with true autosomal recessive microcephaly. Accompanying hypertrophy of retinal pigment epithelium has been described in association with Gardner's syndrome. We present the cases of three siblings (two boys and one girl) with true autosomal recessive microcephaly without mental retardation and without associated systemic anomalies who showed hypertrophy of the retinal pigment epithelium similar to that described in Gardner's syndrome. In the boys, these spots were located on a background of fine variations in pigment, with scattered depigmented atrophic areas revealing the sclera in the peripheral and midperipheral fundus. Superadded white spots were located in front of the retinal vessels. The younger boy also had discrete patches of chorioretinal atrophy of 0.5 to 1 disc diameter. The girl, in addition to the hyperpigmented spots, had a diffuse area of chorioretinal atrophy. The anomalies described above suggest that congenital hypertrophy of the retinal pigment epithelium is not unique to Gardner's syndrome.

A syndrome of alacrima, achalasia, and neurologic anomalies without adrenocortical insufficiency.

We describe a single case of a 2-year, 8-month-old male child with alacrima, achalasia, and neurologic anomalies and proven clinical and laboratory evidence of normal adrenocortical function. As the child was the product of a first cousin marriage, the possibility of autosomal recessive mode of inheritance was considered. Differentiation between this syndrome and other previously described associated syndromes is illustrated. This article emphasizes the presence of multisystem anomalies as described in the presence of normal suprarenal function.
