Genes affected

EGFL8 (HGNC:13944): (EGF like domain multiple 8) Predicted to enable signaling receptor binding activity. Predicted to be involved in anatomical structure development. Predicted to act upstream of or within in utero embryonic development. Predicted to be active in cell surface and extracellular region. [provided by Alliance of Genome Resources, Apr 2022]

EGFL8 links:

PPT2-EGFL8 (HGNC:48343): (PPT2-EGFL8 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring PPT2 (palmitoyl-protein thioesterase 2) and EGFL8 (EGF-like-domain, multiple 8) genes located in the major histocompatibility complex class III region of chromosome 6. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]
