Genes affected

EHMT1 (HGNC:24650): (euchromatic histone lysine methyltransferase 1) The protein encoded by this gene is a histone methyltransferase that methylates the lysine-9 position of histone H3. This action marks the genomic region packaged with these methylated histones for transcriptional repression. This protein may be involved in the silencing of MYC- and E2F-responsive genes and therefore could play a role in the G0/G1 cell cycle transition. Defects in this gene are a cause of chromosome 9q subtelomeric deletion syndrome (9q-syndrome, also known as Kleefstra syndrome). Alternative splicing results in multiple transcript variants.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.20733345).

BP6

Variant 9-137778049-C-T is Benign according to our data. Variant chr9-137778049-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 96147.

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000131 (192/1461632) while in subpopulation EAS AF = 0.00161 (64/39700). AF 95% confidence interval is 0.00129. There are 0 homozygotes in GnomAdExome4. There are 101 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32.

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
