Genes affected
CEBPB (HGNC:1834): (CCAAT enhancer binding protein beta) This intronless gene encodes a transcription factor that contains a basic leucine zipper (bZIP) domain. The encoded protein functions as a homodimer but can also form heterodimers with CCAAT/enhancer-binding proteins alpha, delta, and gamma. Activity of this protein is important in the regulation of genes involved in immune and inflammatory responses, among other processes. The use of alternative in-frame AUG start codons results in multiple protein isoforms, each with distinct biological functions. [provided by RefSeq, Oct 2013]
CEBPB-AS1 (HGNC:51226): (CEBPB antisense RNA 1)

The c.374A>G (p.D125G) alteration is located in exon 1 (coding exon 1) of the CEBPB gene. This alteration results from a A to G substitution at nucleotide position 374, causing the aspartic acid (D) at amino acid position 125 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
