Genes affected
FN3K (HGNC:24822): (fructosamine 3 kinase) A high concentration of glucose can result in non-enzymatic oxidation of proteins by reaction of glucose and lysine residues (glycation). Proteins modified in this way, fructosamines, are less active or functional. This gene encodes an enzyme which catalyzes the phosphorylation of fructosamines which may result in deglycation.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2024The c.440C>T (p.T147M) alteration is located in exon 4 (coding exon 4) of the FN3K gene. This alteration results from a C to T substitution at nucleotide position 440, causing the threonine (T) at amino acid position 147 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
