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]

AUTS2 Gene-Disease associations (from GenCC):

• autism spectrum disorder due to AUTS2 deficiency

  Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), G2P, Orphanet
• syndromic intellectual disability

ACMG classification

Our verdict: Benign. The variant received -7 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.231917).
• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.0000162 (19/1173400) while in subpopulation NFE AF = 0.0000195 (19/975010). AF 95% confidence interval is 0.0000125. There are 0 homozygotes in GnomAdExome4. There are 6 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High AC in GnomAdExome4 at 19 AD gene.
