Purpose: Heterozygous mutations in have been associated with a range of ocular and pituitary abnormalities. We report a novel heterozygous deletion in underlying early-onset retinal dystrophy with atypical maculopathy.
Methods: Clinical examination included electroretinography and multimodal retinal imaging. Molecular genetic testing was composed of next-generation sequencing of a panel of retinal dystrophy genes.
Results: A now 17-year-old boy presented 12 years earlier with a history of progressively poor vision since birth, nyctalopia, and early-onset retinal dystrophy with atypical maculopathy. He also had bilateral microphthalmos and a slim prepubertal appearance; growth hormone levels were within normal ranges. Next-generation sequencing of a retinal dystrophy gene panel revealed a heterozygous deletion c.485delC (p.Pro162G.Infs*24) in exon 5 of .
Conclusions: This second report of maculopathy associated with a heterozygous mutation in confirms that mutations in should be considered in the differential diagnosis of atypical hereditary maculopathy, with or without rod-cone dystrophy.
