The deletion included a total of 19 protein-coding genes listed in RefSeq: EPB41L3, TMEM200C, L3MBTL4, ARHGAP28, LAMA1, LRRC30, PTPRM, RAB12, MTCL1, NDUFV2, ANKRD12, TWSG1, RALBP1, PPP4R1, RAB31, TXNDC2, VAPA, APCDD1, and PIEZO2. The deletion is contained within the 18p region which previously has been associated with autoimmunity and partly overlaps the region associated with thyroid disease as stated in the Chromosome 18 Gene Dosage Map by Cody and colleagues (Supplementary Figure S1) (Hasi-Zogaj et al., 2015; Cody et al., 2018). This evidence concerns the gene PPP4R1 and thyroiditis.
