Variant summary: NOVA2 c.1211G>A (p.Ser404Asn) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The frequency data for this variant in gnomAD is considered unreliable, as metrics indicate poor data quality at this position. To our knowledge, no occurrence of c.1211G>A in individuals affected with Neurodevelopmental Disorder With Or Without Autistic Features And/or Structural Brain Abnormalities and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
