KCNB1 encodes the α-subunit of Kv2.1, the main contributor to neuronal delayed rectifier potassium currents. The subunit consists of six transmembrane α helices (S1-S6), comprising the voltage-sensing domain (S1-S4) and the pore domain (S5-P-S6).

RNU4ATAC, the gene responsible for this disorder, does not encode a protein but instead the U4atac small nuclear RNA (snRNA), a crucial component of the minor spliceosome. Roifman syndrome is an allelic disorder of MOPD I that is characterized by immunodeficiency complications.

Patients And Methods: We investigated GRP78 expression (using immunohistochemistry) in 126 UC-UUTs to assess its relevance to progression. GRP78 overexpression was recognised in 23 (18.
