Neurodevelopmental disorder-craniofacial dysmorphism-cardiac defect-hip dysplasia syndrome due to a point mutation. Two cases - skeletal anomalies, including hip dysplasia, scoliosis, and extra lumbar vertebrae; Two cases reported: 1 had multiple vertebral segmentation defects. One patient had planovalgus feet and crowded toes, whereas the other had postaxial polydactyly and overlapping toes. ?SD, only 2 cases ; Review on behalf of Tracy Lester

Comment on list classification: Source: ClinGen Gene Validity Classification Summary. Determined as MODERATE by calculated classification and MODERATE by Expert curation (dated 11/15/2016). Available here: https://search.clinicalgenome.org/kb/gene-validity/5456. Comments provided by the expert curation: Evidence is rapidly emerging supporting the association between HNRNPK and Au-Kline syndrome. Gallardo et al. published a paper in 2015 describing an Hnrnpk +/- haploinsufficient mouse, which they developed to study its role in tumorigenesis. Personal communication with the senior author of that paper, Sean Post, in August 2016, revealed that the haploinsufficient mice appeared to have "significant reduction in overall size and had numerous structural/bone abnormalities," remniscient of the human phenotype, though he clarified that his group is not able to formally assess them for these types of phenotypes. Additionally, we are aware of at least one additional unpublished case - this evidence is not being formally considered, as it is not part of the public domain.
