Genes affected

TANC2 (HGNC:30212): (tetratricopeptide repeat, ankyrin repeat and coiled-coil containing 2) Predicted to be involved in dense core granule cytoskeletal transport; regulation of dendritic spine development; and regulation of dendritic spine morphogenesis. Predicted to act upstream of or within in utero embryonic development. Located in dendritic spine. [provided by Alliance of Genome Resources, Apr 2022]

TANC2 Gene-Disease associations (from GenCC):

• intellectual developmental disorder with autistic features and language delay, with or without seizures

  Inheritance: AD Classification: DEFINITIVE, STRONG, MODERATE, LIMITED Submitted by: Illumina, Labcorp Genetics (formerly Invitae), G2P, Ambry Genetics, ClinGen
• syndromic intellectual disability

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.235 is higher than 0.05.
