Four other females carrying mutations in Naa10 were reported as having either pectus carinatum or excavatum (Saunier et al., 2016), one of the boys with OS (family 1, individual III-4) was noted to have pectus excavatum, and retrospective review of some of the clinical photographs appears to show mild pectus excavatum in individual III-6 of the same family. This evidence concerns the gene NAA10 and Pectus carinatum.
