Genes affected

NFYC (HGNC:7806): (nuclear transcription factor Y subunit gamma) This gene encodes one subunit of a trimeric complex forming a highly conserved transcription factor that binds with high specificity to CCAAT motifs in the promoters of a variety of genes. The encoded protein, subunit C, forms a tight dimer with the B 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]

The c.577A>G (p.M193V) alteration is located in exon 7 (coding exon 6) of the NFYC gene. This alteration results from a A to G substitution at nucleotide position 577, causing the methionine (M) at amino acid position 193 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
