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 made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.86).
BP6
Variant 9-137716816-G-A is Benign according to our data. Variant chr9-137716816-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 462986.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
Synonymous conserved (PhyloP=-2.17 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000623 (91/1461076) while in subpopulation MID AF= 0.00052 (3/5764). AF 95% confidence interval is 0.000391. There are 0 homozygotes in gnomad4_exome. There are 55 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAd4 at 6 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
