dc.description.abstractWe report on a four-generation inbred family including 10 individuals affected with a form of craniotubular dysplasia (CTD), All affected patients were born to consanguineous healthy parents; this finding, together with the equal sex ratio among affected individuals and the occurrence of only normal individuals among their offspring, indicates that the disease in this family is an autosomal recessive (AR) trait, Taking into account the segregation pattern of the disease in the family and the radiological characteristics of two young CTD patients, the most likely diagnosis for the defect is AR cranio-metaphyseal dysplasia (CMD), CMD is a CTD, with both autosomal dominant (AD) and recessive forms, the description of the present genealogy confirms the AR pattern of inheritance of some cases of CMD and contributes to a better delineation of the clinical spectrum of AR CMD, suggesting a more pronounced diaphyseal involvement in the AR compared with the AD CMD, Through genomewide scanning, we mapped the AR CMD to a 7 cM interval, between D6S302 and D6S1639, at 6q21-22 region, We have also excluded the positional candidate COL10A1 gene as being the responsible for this disorder. Curiously, a form of AR spondylocostal dysplasia (SD) also segregates in the family, including one affected individual with both conditions. the gene DLL3, mapped to 19q13 region, was recently found to be responsible for one form of AR SD; however, we did not find evidence of linkage between this 19q region and the SD segregating in our family, thus implying in genetic heterogeneity for AR SD.
