Comment:

The copy number gain of 4q22.3q25 involves a number of protein-coding genes across multiple chromosomal bands, including six genes associated with autosomal dominant disorders: BMPR1B (OMIM 603248), ADH1C (OMIM 103730), MTTP (OMIM 157147), PPP3CA (OMIM 114105), NFKB1 (OMIM 164011) and SGMS2 (611574).
