Genetic counseling experiences at the University of Cape Town during COVID-19.

Soon after the first COVID-19 case was reported in December 2019 in Wuhan, China, South Africa announced a national lockdown in an attempt to curb the spread of the disease. Under national lockdown, businesses were closed, learning institutions moved to emergency remote teaching (ERT), and hospitals reduced their patient loads. De-escalation of clinical services at Groote Schuur and Red Cross War Memorial Children's Hospitals affected Genetic Counseling Services and resulted in a decrease in in-person and an increase in telecounseling sessions. ERT, offered by the University of Cape Town, affected the teaching of Genetic Counseling students, and other methods of training had to be found to compensate for the lack of patient contact. In this paper, we present our Genetic Counseling team's experiences of learning and clinical services during the COVID-19 pandemic in South Africa. The team met online as a group in November 2020 to discuss their experiences. The discussion was recorded and transcribed, and topics that arose during the discussion were identified. The pandemic and the accompanying lock down, which forced trainees to move back home, resulted in great uncertainty. The trainees found ERT on an online platform, including simulated cases, very helpful, but they lost the confidence to work with real patients. Telecounseling became the predominant form of service delivery and was experienced as positive when video sessions were possible. The telephone service for advanced maternal age counseling was problematic due to unreliable networks. The biggest loss for the GCs was the feeling of disconnection from peers, supervisors, and patients. The experiences highlighted positive and negative aspects as well as specific challenges faced in South Africa. Lessons learnt from the COVID-19 pandemic will be used in future to improve training of GCs and to enhance service delivery.

Novel Two-Component System-Like Elements Reveal Functional Domains Associated with Restriction-Modification Systems and paraMORC ATPases in Bacteria.

Two-component systems (TCS) are important types of machinery allowing for efficient signal recognition and transmission in bacterial cells. The majority of TCSs utilized by bacteria is composed of a sensor histidine kinase (HK) and a cognate response regulator (RR). In the present study, we report two newly predicted protein domains-both to be included in the next release of the Pfam database: Response_reg_2 (PF19192) and HEF_HK (PF19191)-in bacteria which exhibit high structural similarity, respectively, with typical domains of RRs and HKs. Additionally, the genes encoding for the novel predicted domains exhibit a 91.6% linkage observed across 644 genomic regions recovered from 628 different bacterial strains. The remarkable adjacent colocalization between genes carrying Response_reg_2 and HEF_HK in addition to their conserved structural features, which are highly similar to those from well-known HKs and RRs, raises the possibility of Response_reg_2 and HEF_HK constituting a new TCS in bacteria. The genomic regions in which these predicted two-component systems-like are located additionally exhibit an overrepresented presence of restriction-modification (R-M) systems especially the type II R-M. Among these, there is a conspicuous presence of C-5 cytosine-specific DNA methylases which may indicate a functional association with the newly discovered domains. The solid presence of R-M systems and the presence of the GHKL family domain HATPase_c_3 across most of the HEF_HK-containing genes are also indicative that these genes are evolutionarily related to the paraMORC family of ATPases.
