The diagnostic yield when short limbs were the only abnormal sonographic feature reported was 17.9% (30\/168), increasing to 48.9% (23\/47) in the presence of one, and 82.6% (19\/23) in the presence of two or more characteristic features in addition to short limbs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Accurate sonographic phenotyping can maximise the diagnostic yield of NIPD in fetuses suspected to have <jats:italic>FGFR3<\/jats:italic>\u2010related skeletal dysplasias. We suggest that clear guidelines for referral are necessary to increase benefits, decrease costs by preventing unnecessary NIPD, and potentially allow first\u2010line broader spectrum testing for
