Background: The detection of a low amount of viral RNA is crucial to identify a SARS-CoV-2 positive individual harboring a low level of virus, especially during the convalescent period. However, the detection of one gene at high Cycle threshold (Ct) has to be interpreted with caution. In this study we address this specific issue and report our real-life experience. Study design: A total of 1639 nasopharyngeal swabs (NPS) were analyzed with Xpert® Xpress SARS-CoV-2.

The CFDP1 proteins have been linked to craniofacial development and osteogenesis in vertebrates, though
specific human syndromes have not yet been identified. Alterations of craniofacial development represent the
main cause of infant disability and mortality in humans. For this reason, it is crucial to understand the cellular
functions and mechanism of action of the CFDP1 protein in model vertebrate organisms. Using a combination of
genomic, molecular and cell biology approaches, we have performed a functional analysis of the cfdp1 gene and
