Genes affected
PROKR1 (HGNC:4524): (prokineticin receptor 1) This gene encodes a member of the G-protein-coupled receptor family. The encoded protein binds to prokineticins (1 and 2), leading to the activation of MAPK and STAT signaling pathways. Prokineticins are protein ligands involved in angiogenesis and inflammation. The encoded protein is expressed in peripheral tissues such as those comprising the circulatory system, lungs, reproductive system, endocrine system and the gastrointestinal system. The protein may be involved in signaling in human fetal ovary during initiation of primordial follicle formation. Sequence variants in this gene may be associated with recurrent miscarriage.

APLF (HGNC:28724): (aprataxin and PNKP like factor) Enables DNA-(apurinic or apyrimidinic site) endonuclease activity; nuclease activity; and nucleotide binding activity. Involved in double-strand break repair via nonhomologous end joining and single strand break repair. Acts upstream of or within positive regulation of DNA ligation. Located in nucleoplasm. Is active in site of double-strand break. [provided by Alliance of Genome Resources, Apr 2022]
