Genes affected

AUTS2 (HGNC:14262): (activator of transcription and developmental regulator AUTS2) This gene has been implicated in neurodevelopment and as a candidate gene for numerous neurological disorders, including autism spectrum disorders, intellectual disability, and developmental delay. Mutations in this gene have also been associated with non-neurological disorders, such as acute lymphoblastic leukemia, aging of the skin, early-onset androgenetic alopecia, and certain cancers. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PVS1: Start lost variant, next in-frame start position is after 2 pathogenic variants. Next in-frame start position is after 93 codons. Genomic position: 69599930. Lost 0.073 part of the original CDS.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 7-69599655-T-C is Pathogenic according to our data. Variant chr7-69599655-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 1033782.Status of the report is criteria_provided_single_submitter, 1 stars.
