Genes affected
NIFK (HGNC:17838): (nucleolar protein interacting with the FHA domain of MKI67) This gene encodes a protein that interacts with the forkhead-associated domain of the Ki-67 antigen. The encoded protein may bind RNA and may play a role in mitosis and cell cycle progression. Multiple pseudogenes exist on chromosomes 5, 10, 12, 15, and 19.[provided by RefSeq, Jan 2009]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.608C>T (p.T203M) alteration is located in exon 5 (coding exon 5) of the NIFK gene. This alteration results from a C to T substitution at nucleotide position 608, causing the threonine (T) at amino acid position 203 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
