Whole exome and Sanger sequencing revealed that the one with a novel heterozygous missense (c.2017G>T, p.Gly673Cys) mutation in LTBP3 had clinical features consistent with acromicric dysplasia (ACMICD).
A heterozygous missense mutation (exon 14: c.2087C>G: p.Ser696Cys) in latent transforming growth factor β (TGF-β)-binding protein-3 (LTBP3) was identified in a dominant AD family.
