Genes affected
ATOH7 (HGNC:13907): (atonal bHLH transcription factor 7) This intronless gene encodes a member of the basic helix-loop-helix family of transcription factors, with similarity to Drosophila atonal gene that controls photoreceptor development. Studies in mice suggest that this gene plays a central role in retinal ganglion cell and optic nerve formation. Mutations in this gene are associated with nonsyndromic congenital retinal nonattachment. [provided by RefSeq, Dec 2011]

This sequence change creates a premature translational stop signal (p.Pro18Argfs*69) in the ATOH7 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 135 amino acid(s) of the ATOH7 protein. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 144066). This premature translational stop signal has been observed in individual(s) with clinical features of persistent hyperplasia of the primary vitreous (PMID: 22068589). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs587777665, gnomAD 0.006%). -
