Genes affected

ANKHD1-EIF4EBP3 (HGNC:):

ANKHD1-EIF4EBP3 links:

EIF4EBP3 (HGNC:3290): (eukaryotic translation initiation factor 4E binding protein 3) This gene encodes a member of the EIF4EBP family, which consists of proteins that bind to eukaryotic translation initiation factor 4E and regulate its assembly into EIF4F, the multi-subunit translation initiation factor that recognizes the mRNA cap structure. Read-through transcription from the neighboring upstream gene (MASK or ANKHD1) generates a transcript (MASK-BP3) that encodes a protein comprised of the MASK protein sequence for the majority of the protein and a different C-terminus due to an alternate reading frame for the EIF4EBP3 segments. [provided by RefSeq, Oct 2010]

EIF4EBP3 links:

SRA1 (HGNC:11281): (steroid receptor RNA activator 1) Both long non-coding and protein-coding RNAs are transcribed from this gene, and they represent alternatively spliced transcript variants. This gene was initially defined as a non-coding RNA, which is a coactivator for several nuclear receptors (NRs) and is associated with breast cancer. It has now been found that this gene is involved in the regulation of many NR and non-NR activities, including metabolism, adipogenesis and chromatin organization. The long non-coding RNA transcripts interact with a variety of proteins, including the protein encoded by this gene. The encoded protein acts as a transcriptional repressor by binding to the non-coding RNA. [provided by RefSeq, Mar 2012]

The c.7681C>A (p.H2561N) alteration is located in exon 35 (coding exon 35) of the ANKHD1-EIF4EBP3 gene. This alteration results from a C to A substitution at nucleotide position 7681, causing the histidine (H) at amino acid position 2561 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
