Genes affected

KDM6B (HGNC:29012): (lysine demethylase 6B) The protein encoded by this gene is a lysine-specific demethylase that specifically demethylates di- or tri-methylated lysine 27 of histone H3 (H3K27me2 or H3K27me3). H3K27 trimethylation is a repressive epigenetic mark controlling chromatin organization and gene silencing. This protein can also demethylate non-histone proteins such as retinoblastoma protein. Through its demethylation actvity this gene influences cellular differentiation and development, tumorigenesis, inflammatory diseases, and neurodegenerative diseases. This protein has two classical nuclear localization signals at its N-terminus. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Feb 2017]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1746271).

BP6

Variant 17-7845595-G-A is Benign according to our data. Variant chr17-7845595-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 3049542.Status of the report is no_assertion_criteria_provided, 0 stars.

BS2

High AC in GnomAd4 at 13 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
