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

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.20279568).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000287 (42/1460978) while in subpopulation NFE AF= 0.0000369 (41/1111274). AF 95% confidence interval is 0.0000274. There are 0 homozygotes in gnomad4_exome. There are 24 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAd4 at 5 AD gene.
