FOXP1 Variant analysis (a) Exon map of FOXP1, including the 3′ UTR identifying the location of variants reported in Patient 1 (rs886058828) and his father (rs143202281). (b) Mother, sister, Patient 1, and father's Sanger sequencing results, respectively. Heterozygous insertion and deletion variants were reported in Patient 1 (NM_032682.5:c.3413_3414del) and his father (NM_032682.5:c.3413_3414dup). (c) Multiple sequence alignment of region of interest of the four family members, Hsa samples (1.) mother (2.) sister (3.) Patient 1 (4.) father
