Genes affected

SGK1 (HGNC:10810): (serum/glucocorticoid regulated kinase 1) This gene encodes a serine/threonine protein kinase that plays an important role in cellular stress response. This kinase activates certain potassium, sodium, and chloride channels, suggesting an involvement in the regulation of processes such as cell survival, neuronal excitability, and renal sodium excretion. High levels of expression of this gene may contribute to conditions such as hypertension and diabetic nephropathy. Several alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2009]

The c.772C>T (p.H258Y) alteration is located in exon 8 (coding exon 8) of the SGK1 gene. This alteration results from a C to T substitution at nucleotide position 772, causing the histidine (H) at amino acid position 258 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
