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]

KDM5C (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KDM5C. . Gene score misZ 5.1452 (greater than the threshold 3.09). GenCC has associacion of gene with X-linked syndromic intellectual disability, syndromic X-linked intellectual disability Claes-Jensen type.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.924
• PP5: Variant X-53211545-G-C is Pathogenic according to our data. Variant chrX-53211545-G-C is described in ClinVar as [Pathogenic]. Clinvar id is 9776.Status of the report is no_assertion_criteria_provided, 0 stars.
