Weakness
By searching for additional XRCC4-interacting factors, we identified a previously uncharacterized 33 kDa protein, XRCC4-like factor (XLF, also named Cernunnos), that has weak sequence homology with XRCC4 and is predicted to display structural similarity [scienceopen.com]
[…] worsens over time. [16] Using a human induced pluripotent stem cell model of NHEJ1 deficiency, it was shown that NHEJ1 has an important role in promoting survival of the primitive hematopoietic progenitors. [17] These NHEJ1 deficient cells possess a weak [ipfs.io]

Our results demonstratethat XLF-iPSCs possess a weak NHEJ-mediated DNArepair capacity that is incapable of coping with the DNAlesions introduced by physiological stress, normal metabo-lism, and ionizing radiation. [documents.tips]

21), EEC syndrome ( TP63 ) Genetic defects that may be variably associated with T-cell lymphopenia, but are not likely to be identified by newborn screening for SCID. [aacc.org]
Treatment
Two yr after HSCT, the patient maintains full donor engraftment, normal hematopoiesis, and progressively improving immune competence, thus suggesting that HSCT may be the treatment of choice for CSy. [ncbi.nlm.nih.gov]
This therapy may provide partial immune recovery until other treatment options become available or the patient becomes non-responsive to the enzyme therapy. Another emerging treatment for SCID is gene therapy. [aacc.org]
Fully matched donor screening is in progress for bone marrow transplantation which is curative treatment of the disease. [scienceopen.com]
He is also investigating photolysis of non‐biological compounds such as 8‐methoxypsoralen UVA, mitomycin C, and nitrogen mustard and their importance in psoriasis treatment and in Fanconi anemia. [books.google.com]
Etiology
Researchers continue to identify SCID-associated gene defects; however, the genetic etiology remains unknown for a subset of clinically classified SCID patients. [aacc.org]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
However, the identification of definitive susceptibility genes for these etiologically complex disorders remains elusive. [worldwidescience.org]
Progress in the biochemistry and genetics of NHEJ and of human SCID has proven to be synergistic between these two fields in a manner that covers the range from biochemical etiology to considerations about possible gene therapy for the B SCID patients [doi.org]
Pathophysiology
Since the appearance of the last classification in 2007, novel forms of PID have been discovered, and additional pathophysiology mechanisms that account for PID in human beings have been unraveled. [scienceopen.com]
Although the book’s primary focus is on practical diagnosis and management, the pathophysiology of PID is also discussed. [books.google.es]
Here, we address the emerging role of medial OFC, amygdala, and ventral tegmental area projections to the ventral striatum (VS) in OCD pathophysiology. [worldwidescience.org]
Pathophysiology: Most primary immune deficiencies (PIDs) arise from genetic mutations that result in defects in the generation, function, or regulation of a cellular constituent of the immune system. [cancertherapyadvisor.com]

We conclude that, in mice, Cernunnos-XLF is essential for normal NHEJ-mediated repair of DNA DSBs and that Cernunnos-XLF acts as a genomic caretaker to prevent genomic instability. Proc. Natl. Acad. Sci. [uniprot.org]
Our lab is interested in understanding how mammalian cells sense DNA double stand breaks, integrate cell cycle progression and cellular survival to facilitate high-fidelity repair and to prevent oncogenic transformation. [talent.sciencenet.cn]
