GARD : ²⁰ The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 3258 Definition Cenani-Lenz syndrome (CLS) is a congenital malformation syndrome that associates a complex syndactyly of the hands with malformations of the forearm bones and similar manifestations in the lower limbs. Epidemiology Fewer than 30 cases have been described and the exact incidence has not been evaluated. The majority of cases occurred in related families. Clinical description Classical CLS is characterized by the almost symmetrical presence of a total fusion of fingers and synostosis of the hand bones, giving the hands a mitten-like appearance. A variant of the syndrome, with oligodactyly and partial syndactyly, has been reported. The following features characterize the syndrome: carpal, metacarpal and digital synostoses, disorganization of the carpal bones, numeric reduction of the digital rays and toe syndactyly. Other features are radioulnar synostosis with shortening of the radius and ulna, brachymesomelia, radius head dislocation and metatarsal synostoses. The syndrome affects both the upper and lower limbs but, in general, the latter are less severely affected. Associated malformations (renal hypoplasia and vertebral and hemivertebral anomalies) have occasionally been reported. A few publications associate CLS with other, more frequent, forms of syndactyly. Mild facial dysmorphism ( ptosis, high-arched palate, high, broad and prominent forehead, hypertelorism, flat nasal bridge, down slanting palpebral fissures, short nose, short prominent philtrum and malar hypoplasia) has been described in isolated cases. Etiology The disease is transmitted as an autosomal recessive trait. Homozygous or compound heterozygous mutations of the LRP4 gene (11p12-p11.2) have been identified. A heterozygous duplication of 1.7 Mb covering the GREM1 and FMN1 genes has also been reported in a CLS-like form of the syndrome. Diagnostic methods Diagnosis is essentially clinical. Differential diagnosis CLS can be distinguished clinically from other limb malformations. Antenatal diagnosis Diagnosis can be suspected antenatally by ultrasonography. As an autosomal recessive syndrome, recurrence risk for CLS is 25% for a subsequent pregnancy. Management and treatment Surgical treatment with reconstruction of an individualized finger is recommended but the functional results of syndactyly release may be unsatisfactory. Prognosis Functional prognosis depends on the specific limb anomalies of the patient.

MalaCards based summary : Cenani-Lenz Syndactyly Syndrome, also known as syndactyly type 7, is related to chromosome 2q35 duplication syndrome and renal hypodysplasia/aplasia 1. An important gene associated with Cenani-Lenz Syndactyly Syndrome is LRP4 (LDL Receptor Related Protein 4), and among its related pathways/superpathways are Wnt / Hedgehog / Notch and Wnt Signaling Pathway and Pluripotency. Affiliated tissues include thymus, bone and kidney, and related phenotypes are frontal bossing and finger syndactyly

Disease Ontology : ¹² A dysostosis characterized by syndactyly, malformation of the forearm and lower limb bones, renal hypoplasia or aplasia and that has material basis in homozygous or compound heterozygous mutation in the LRP4 gene on chromosome 11p11.

KEGG : ³⁶ Cenani-Lenz syndactyly syndrome is an autosomal-recessive congenital malformation syndrome characterized by syndactyly and/or oligodactyly and kidney anomalies. The cause of Cenani-Lenz syndactyly syndrome is LRP4, a low-density lipoprotein receptor that modulates Wnt signaling.

UniProtKB/Swiss-Prot : ⁷² Cenani-Lenz syndactyly syndrome: A congenital malformation syndrome defined as complete and complex syndactyly of the hands combined with malformations of the forearm bones and similar manifestations in the lower limbs. It is characterized by fusion and disorganization of metacarpal and phalangeal bones, radius and ulnar shortening, radioulnar synostosis, and severe syndactyly of hands and feet.
