FLNA and skeletal dysplasia: Other diseases, such as STING-associated vasculopathy with onset in infancy (SAVI) and COPA syndrome, which may present with early-onset ILD and occasionally accompanied by neurological involvement, and FLNA mutations, which may cause ILD, skeletal dysplasia, neuronal migration abnormality, cardiovascular malformation, intellectual disability, and intestinal obstruction (16), should also be excluded as differential diagnoses.
