"Mirror movements" are an axonal guidance disorder that consists of involuntary contralateral movements that mimic unilateral intentional ones, typically involving the fingers of the hand. They can be isolated or associated with conditions such as Klippel-Feil syndrome, Kallmann syndrome, or congenital hemiplegia. Isolated congenital mirror movements are sometimes caused by autosomal dominant mutation in the genes DCC or RAD51. At least 4 previously reported cases had strabismus, 3 with Moebius syndrome and 1 with Duane retraction syndrome. We report the case of a boy with an unusual incomitant strabismus consistent with orbital dysinnervation and suggest that for some patients with congenital mirror movements the neurological miswiring extends to the orbit, causing congenital cranial dysinnervation disorder.

RAD51 is the only identified autosomal dominant gene to date causative of Fanconi anemia (FA) due to dominant negative effects. Only two patients with RAD51-associated FA have been reported with atypical FA phenotypes without bone marrow failure. We describe a new Asian patient with a novel RAD51 mutation, presenting with multiple congenital anomalies and atypical FA with chromosomal instability. The patient was a 9-year-old Japanese girl. She had strabismus, myopia, submucous cleft palate, bilateral hearing impairment, and scoliosis. She also had growth retardation, developmental delay, and severe intellectual disability. We performed trio whole exome sequencing and Sanger sequencing and identified a de novo RAD51 mutation (c.725A>G, p.Gln242Arg). Isolated lymphocytes from the patient were hypersensitive to chromosomal breakage induced by the DNA cross-linking agent, mitomycin C. Our detailed phenotypic analysis of the RAD51-associated atypical FA revealed clinical manifestations from the diverse population and a consistent FA phenotype characterized by chromosome instability, intellectual disability, radial ray abnormality, and microcephaly, but not bone marrow failure.
