A family showing apparent X linked inheritance of both anencephaly and spina bifida.
A family is reported which includes five males, two with spina bifida, two sibs with anencephaly, and one with both high and low spinal lesions. The affected subjects came from four sibships in three generations. The mode of inheritance of these neural tube defects is consistent with X linkage.
متن کاملBrief communication: possible X-linked anencephaly and spina bifida--report of a kindred.
Causal heterogeneity of anencephaly and spina bifida has been demonstrated; in rare families the neural tube defect may be caused by a single gene. We report a family in which four cases of anencephaly or spina bifida may represent X-linked inheritance.
متن کاملAnencephaly and spina bifida (ASB) and retroversion.
Despite the wealth of epidemiological material of the last decade, birth defects are still the chief cause of perinatal mortality and no significant breakthrough in understanding or reduction has yet been seen. Many proposed aetiological factors are still being evaluated. This report suggests a possible, simple, remediable factor in the aetiology of defects of the central nervous system.
متن کاملSpina bifida and anencephaly in Scotland.
Data obtained from routine sources showed that from 1971 to 1982 the birth prevalences of spina bifida and anencephaly in Scotland fell. When known terminations after routine alpha fetoprotein screening were added to total births the adjusted birth prevalence could be calculated. In 1974-82 this fell by 40% for spina bifida (3 X 0-1 X 8) and 36% for anencephaly (2 X 2-1 X 4). These findings wer...
متن کاملSpina bifida and anencephaly: are miscarriages a possible cause?
The marriage-to-conception interval in 151 pregnancies producing infants with anencephaly or spina bifida was not significantly different from that in 218 pregnancies resulting in normal infants. Significantly more miscarriages occurred before than after the birth of 285 infants with anencephaly or spina bifida, but in 133 controls no before-after difference was observed. These observations see...
