TCF12 and craniosynostosis: In parallel to this work, targeted sequencing of DNA samples of 160 British unrelated subjects with craniosynostosis, including the coronal suture, and previously negative testing of the FGFR2, FGFR3, TWIST1, and TCF12 genes, was carried out by capturing the TCF12 genomic region (chr15: 57,029,979‐57,670,037) using the SeqCap EZ Choice Library system (Roche‐Nimblegen, Inc., Madison, WI).
