SUMMARY.
Algerian-Icelandic Famil-y with
Hereditary Elliptocytosis.
The paper contains summarized
clinical histories, hæmatological
observations, biochemical and
serological genetic data on the
family described.
The propositus, 3 months old
boy, has a moderate hæmolytic
anæmia. His father, an Algerian,
has elliptocytosis, but no anæmia
and no signs of hæmolysis. His
Icelandic wife has morphological-
ly normal red corpuscles, but his-
tory of anæmia without a known
cause and mild anæmia at the
time of the investigation. Their
daughter is hæmatologically nor-
mal. The test for sickling (wet
wax-sealed preparation) was nega-
tive in all members of the family.
The genetic data collected are not
suggestive of linkage between the
elliptocytic main locus and the
Rh system. Other bloodgroup and
biochemical systems used as mar-
ker loci are considered uninforma-
tive from linkage point of view.
The main points discussed are:
1) Age and onset of the ellipto-
cytic change. 2) The hypothesis
of two different ,,normal“ alleles
(el,, eh) of the unaffected parent
and possible consequences. 3)
Short explanatory comments are
made on the various inherited bio-
chemical systems investigated in
the family.
The author has no knowledge
of the occurrence of hereditary el-
liptocytosis in Algeria.
