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]

ATOH7 Gene-Disease associations (from GenCC):

• persistent hyperplastic primary vitreous, autosomal recessive

  Inheritance: Unknown, AR Classification: STRONG, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), G2P
• persistent hyperplastic primary vitreous

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM1: In a chain Transcription factor ATOH7 (size 151) in uniprot entity ATOH7_HUMAN there are 4 pathogenic changes around while only 1 benign (80%) in NM_145178.4
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 4 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.30531 (below the threshold of 3.09). Trascript score misZ: -1.2226 (below the threshold of 3.09). GenCC associations: The gene is linked to persistent hyperplastic primary vitreous, autosomal recessive, persistent hyperplastic primary vitreous, anterior segment dysgenesis 7.
• BP4: Computational evidence support a benign effect (MetaRNN=0.0712516).
