Specifically, it can be done through detecting mutations in the CKAP2L gene, of which a total of eight causative variants having been identified.Genetic testing of Filippi Syndrome makes use of three major techniques:

Whole Exome Sequencing, which focuses on sequencing the exons in the region of the genome coding for proteins. Next-generation Sequencing, which is a high-throughput genomic sequence analysis method that make use of flow cytometry, and is able to analyze gigabases of sequences in one instrument run. Array Based Techniques, which makes use of microarray applications to determine chromosomal abnormalities with greater precision compare to the conventional karyotyping tests. Treatment
Currently, Filippi Syndrome has no direct cure. It is treated according to observed symptoms on affected individuals. Syndactyly release surgery
Syndactyly exhibit varying degrees of severity in individuals. Hence not all affected individuals with this condition must undergo surgical intervention. For example, syndactyly that occurs at the proximal end of the digits may have limited effect on the normal functioning of the hand and foot, and correction through surgery is optional.Simple syndactyly is the condition of cutaneous fusion between two digits, and can be treated by surgically rebuilding the hourglass shape web space between digits. During surgery, incision is first carried out to separate the fused fingers. It is followed by reconstruction of the web spaces side walls using dorsal advancement flaps or skin grafts obtained from the affected individuals groin.
