Genes affected
FETUB (HGNC:3658): (fetuin B) The protein encoded by this gene is a member of the fetuin family, part of the cystatin superfamily of cysteine protease inhibitors. Fetuins have been implicated in several diverse functions, including osteogenesis and bone resorption, regulation of the insulin and hepatocyte growth factor receptors, and response to systemic inflammation. This protein may be secreted by cells. [provided by RefSeq, Jul 2008]
HRG-AS1 (HGNC:55915): (HRG and FETUB antisense RNA 1)

Collection Method: clinical testing

The c.73G>A (p.A25T) alteration is located in exon 1 (coding exon 1) of the FETUB gene. This alteration results from a G to A substitution at nucleotide position 73, causing the alanine (A) at amino acid position 25 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
