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 Likely_benign. Variant got -5 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.21500903).
BP6
Variant 9-137716945-G-T is Benign according to our data. Variant chr9-137716945-G-T is described in ClinVar as [Likely_benign]. Clinvar id is 365995.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr9-137716945-G-T is described in Lovd as [Likely_benign].
BS2
High AC in GnomAd4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
