Other genes that were identified as candidates for adaptive introgression include a region identified in PEL and MXL that contains FARP2 (regulates cytoskeletal formation), a region in PEL and MXL that contains PAX3 (a transcription factor important to development), a region in PEL and MXL that contains CNTNAP2 (which affects cell receptors in the nervous system and has been implicated in neurodevelopmental disorders), and a region in PEL that contains MYOCD, a gene involved in cardiac function (fig. Here, CNTNAP2 is linked to neurodevelopmental disorder.
