Abstract

In the present study we describe the exome sequencing and analysis of a patient with Catel-Manzke-like phenotype showing bilateral hyperphalangism of the second finger and thumb clinodactyly due to a unilateral delta phalanx, associated with growth, cardiac and vertebral defects. The exome sequencing analysis excluded pathogenetic mutations in the genes known to cause syndromes with hyperphalangism and did not identify any alteration in the X-chromosome or de novo mutations in likely candidate genes. Under the assumption of an autosomal recessive mode of inheritance and based on the frequency of the single nucleotide variants found in homozygous or double heterozygous states and the results of computer prediction programs, only one gene, DNAH10, emerged as a candidate in the pathogenesis of the disease in our patient. However, the differences among the known biological functions of DNAH10 and the genes involved in the other syndromes with hyperphalangism, suggest caution in the interpretation of the results.
