Genes affected
CHD2 (HGNC:1917): (chromodomain helicase DNA binding protein 2) The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CHD2. . Gene score misZ: 5.2052 (greater than the threshold 3.09). Trascript score misZ: 6.0204 (greater than threshold 3.09). The gene has 57 curated pathogenic missense variants (we use a threshold of 10). The gene has 104 curated benign missense variants. GenCC has associacion of the gene with developmental and epileptic encephalopathy 94, complex neurodevelopmental disorder, myoclonic-astatic epilepsy, Lennox-Gastaut syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.3408516).
BP6
Variant 15-92946064-A-C is Benign according to our data. Variant chr15-92946064-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 474374.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High AC in GnomAdExome4 at 21 AD gene.
