Abstract

This study was undertaken to establish the prevalence rates at birth of the skeletal dysplasias that can be recognised in the perinatal period. Using the data base of the Latin-American Collaborative Study of Congenital Malformations (ECLAMC), for the years 1978 to 1983, on 349 470 births (live and stillbirths), a crude prevalence rate of 2.3/10 000 was observed. However, several indications of under-registration suggest that the real value is about twice that observed. The most frequent types of skeletal dysplasia were achondroplasia, with a prevalence rate between 0.5 and 1.5/10 000 births, the thanatophoric dysplasia/achondrogenesis group (0.2 and 0.5/10 000 births), and osteogenesis imperfecta (0.4/10 000 births). The mutation rate for autosomal dominant achondroplasia was estimated at between 1.72 and 5.57 X 10(-5) per gamete per generation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
