ABSTRACT
Congenital cutis laxa is an exceptional conditionn. No large scale pedigree has been reported from Iran. We report a family with 106 members with two members affected with cutis laxa. Our cases were two patients [male and female] with pre- and postnatal growth retardation, cutis laxa, characteristic facies and otherr manifestations which proved that they were affected with cutis laxa. Their family history was studied and a large pedigree was drawn up. Baseddd on the findings in their pedigree pattern, in addition to clinical pathological studies, one can say that cutis laxa in this family is autosomal recessive. We also showed obligate carrier members in the family. Recent studies have shown that cutis laxa is a heterogeneous group of conditions both clinically and genetically. Autosomal dominant, autosomal recessive, X-linked and also acquired forms have been reported. Our study indicates that our case is an autosomal recessive type I. We disussed the pedigree that covers five generations
