ENST00000700753.1:c.121G>C

Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBS1_Supporting

The ENST00000700753.1(CHD3):​c.121G>C​(p.Glu41Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000119 in 1,410,516 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E41K) has been classified as Uncertain significance.

Genes affected
CHD3 (HGNC:1918): (chromodomain helicase DNA binding protein 3) This gene encodes a member of the CHD family of proteins which are characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. This protein is one of the components of a histone deacetylase complex referred to as the Mi-2/NuRD complex which participates in the remodeling of chromatin by deacetylating histones. Chromatin remodeling is essential for many processes including transcription. Autoantibodies against this protein are found in a subset of patients with dermatomyositis. Three alternatively spliced transcripts encoding different isoforms have been described. [provided by RefSeq, Jul 2008]
NAA38 (HGNC:28212): (N-alpha-acetyltransferase 38, NatC auxiliary subunit) Involved in negative regulation of apoptotic process. Located in cytoplasm and nucleoplasm. Part of NatC complex. Colocalizes with polysome. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.14721254).
BS1
Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000126 (159/1260724) while in subpopulation NFE AF = 0.000148 (149/1005122). AF 95% confidence interval is 0.000129. There are 0 homozygotes in GnomAdExome4. There are 71 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
