Associated with Oculoskeletodental syndrome #618440 (AR) in OMIM. This is based on evidence from PMID: 31034465 - Tiosano et al 2019 - report 5 individuals from 3 unrelated consanguineous families with a similar set of clinical features including dysmorphic facial features, short stature, skeletal and neurological abnormalities, and cataracts. The skeletal findings included "scoliosis, delayed bone age, diminished ossification of femoral heads, cervical lordosis, shortened fifth digits with mild metaphyseal dysplasia and clinodactyly". Homozygous loss-of-function mutations in PIK3C2A were identified in each family.
The authors found that PIK3C2A is critical for the formation of cilia and therefore is appropriate for inclusion on the skeletal ciliopathy panel.
