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 Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CHD1. . Trascript score misZ 3.2778 (greater than threshold 3.09). GenCC has associacion of gene with Pilarowski-Bjornsson syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.29994977).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.5042A>G (p.Q1681R) alteration is located in exon 35 (coding exon 35) of the CHD1 gene. This alteration results from a A to G substitution at nucleotide position 5042, causing the glutamine (Q) at amino acid position 1681 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
