Abstract:
Polydactyly is defined as an extra finger or toe that is present at birth. It is a congenital anomaly that can manifest as a single disorder or as a component of a syndrome. Treatment can be conservative or operative depending on the anticipated function of the extra digit. In this report, we describe a case of a bifid 5th digit on the right hand. The aim of this report was to report a new variant of type IIIB described by Duran (2015). This will possibly lead to the modification of the current classifications, which will improve the diagnosis and treatment of patients.

The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...
