Genes affected

CHD1 (HGNC:1915): (chromodomain helicase DNA binding protein 1) 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. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_001270.4. Strenght limited to Supporting due to length of the change: 1aa.
• BP6: Variant 5-98856460-AAGG-A is Benign according to our data. Variant chr5-98856460-AAGG-A is described in ClinVar as [Benign]. Clinvar id is 1249419.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.33 is higher than 0.05.
