Professional Statement
Genomic Disorders: The main areas of focus in our research is the pathogenetics of lung development, and, in particular, the role of non-coding regulatory elements. We demonstrated that haploinsufficiency of the transcriptional factor FOXF1 gene on 16q24.1 results in a lethal neonatal diffuse developmental lung disorder, alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV). Recently, we unraveled the role of the TBX4 and FGF10 genes in other developmental lung diseases, including acinar dysplasia and congenital alveolar dysplasia.We found that somatic mosaicism for CNVs that also contribute to the germline mosaicism is significantly more common than previously thought. We showed that a considerable number of apparently de novo mutations causing genomic disorders occur in the previous generation as a low-level somatic mosaicism and can thus be recurrently transmitted to future offspring. We continue to study the scale and clinical importance of this phenomenon.
Moreover, we investigate the molecular mechanisms and phenotypic consequences of genomic rearrangements. We are particularly interested in elucidating the role of higher-order genomic architectural features such as low-copy repeats (LCRs) and repetitive elements (LINEs, Alus, HERVs) in genomic instability. Recently, we reported the role of BPTF, PSMD12, and TRIP12 in neurodevelopmental disorders.
