Genes affected

NFYB (HGNC:7805): (nuclear transcription factor Y subunit beta) The protein encoded by this gene is one subunit of a trimeric complex, forming a highly conserved transcription factor that binds with high specificity to CCAAT motifs in the promoter regions in a variety of genes. This gene product, subunit B, forms a tight dimer with the C subunit, a prerequisite for subunit A association. The resulting trimer binds to DNA with high specificity and affinity. Subunits B and C each contain a histone-like motif. Observation of the histone nature of these subunits is supported by two types of evidence; protein sequence alignments and experiments with mutants. [provided by RefSeq, Jul 2008]

The c.268G>A (p.V90I) alteration is located in exon 5 (coding exon 4) of the NFYB gene. This alteration results from a G to A substitution at nucleotide position 268, causing the valine (V) at amino acid position 90 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
