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 Benign. Variant got -15 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). GenCC has associacion of gene with developmental and epileptic encephalopathy 94, complex neurodevelopmental disorder, myoclonic-astatic epilepsy, Lennox-Gastaut syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.029762983).
BP6
Variant 15-92943065-A-T is Benign according to our data. Variant chr15-92943065-A-T is described in ClinVar as [Likely_benign]. Clinvar id is 585667.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS2
High AC in GnomAd4 at 8 AD gene.
