(A) Family pedigree and Sanger sequencing results of the CREBBP variant. The arrows indicate the variant c.3235C>T in the siblings. (B,C) Photos of the two siblings. (D,E) Hand morphology of the two siblings. Typical features include broad and angulated thumbs. (F) Sequence read alignment of the c.3235C>T (16:3817736:G>A) site from the BAM files of trio whole-exome sequencing using Integrative Genomics Viewer (v2.8.1) indicated a variant allele fraction for c.3235C>T of ~50% in the siblings but not in the parents. (G) Sequence read alignment of the c.3235C>T (16:3817736:G>A) site from the BAM files of high-depth next-generation sequencing using Integrative Genomics Viewer (v2.8.1) indicated a variant allele fraction for c.3235C>T of ~3.64% (336/9225 reads) and 1.94% (173/8896 reads) in the peripheral blood and buccal mucosa of the mother, respectively.
