Genes affected

KDM5C (HGNC:11114): (lysine demethylase 5C) This gene is a member of the SMCY homolog family and encodes a protein with one ARID domain, one JmjC domain, one JmjN domain and two PHD-type zinc fingers. The DNA-binding motifs suggest this protein is involved in the regulation of transcription and chromatin remodeling. Mutations in this gene have been associated with X-linked cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2009]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, KDM5C
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.956
• PP5: Variant X-53220843-A-G is Pathogenic according to our data. Variant chrX-53220843-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 377331.Status of the report is criteria_provided_single_submitter, 1 stars.
