  • Normal test results are highlighted in bold. Normal range for nNO is above 77 nL/min. Local normal range for CBF is 8.5-16.8 Hz.

  • Segregation analysis using available parental samples indicated by M (mother is carrier), P (father is carrier) or B (both parents carriers), unaffected siblings have not been tested.

  • Age diag, age diagnosis confirmed; CBF, ciliary beat frequency; CHD, congenital heart defects; F, female; IDA, inner dynein arms; M, male; ND, not done; NO, nitric oxide; ODA, outer dynein arms; SI, situs inversus; Sib, sibling of; SS, situs solitus; WES, whole exome sequencing.
