Three overlapping regions were detected on this chromosome: one near the UFM1 gene involved in brain development and abnormalities in humans [21]; the second, near neurobeachin (NBEA), a gene previously associated with autism in humans [22] and wool production traits in sheep [23]; and the last, near RXFP2, involved in formation of horns in sheep [24] and cattle [25]. The gene discussed is RXFP2; the disease is autism.
