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]

The c.455C>T (p.T152I) alteration is located in exon 1 (coding exon 1) of the ATOH7 gene. This alteration results from a C to T substitution at nucleotide position 455, causing the threonine (T) at amino acid position 152 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 152 of the ATOH7 protein (p.Thr152Ile). This variant is present in population databases (rs555446400, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with ATOH7-related conditions. ClinVar contains an entry for this variant (Variation ID: 1460888). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
