A Novel SOX18 Mutation Uncovered in Jordanian Patient with Hypotrichosis-Lymphedema-Telangiectasia Syndrome by Whole Exome Sequencing
Molecular and Cellular Probes 30 (2016)
The SOX18 gene encodes a transcription factor that plays a notable role in certain developmental contexts such as lymphangiogenesis, hair follicle development and vasculogenesis. SOX18 mutations are linked to recessive and dominant hypotrichosis-lymphedema-telangiectasia syndrome (HLTS). In this study we report on a novel heterozygous mutation in SOX18 in a Jordanian patient suffering from HLTS that was revealed by Whole Exome Sequencing. In this case, a frameshift caused by 14-nucleotide duplication in SOX18 appeared de novo resulting in a premature translational stop at the N-terminal region of the central trans-activation domain. Here we present the clinical manifestations of the above mentioned molecular lesion in the light of what is known from published SOX18 mutations.
