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]

The c.2785C>G variant is not present in publicly available population databases like EVS, Indian Exome Database or our in-house exome database. The variant is present in 1000 Genomes, ExAC and gnomAD at a low frequency. This variant has neither been published in literature nor reported to the ClinVar, Human Genome Mutation Database (HGMD) or OMIM databases, in any affected individuals. Predictions from different in-silico pathogenicity prediction programs like SIFT, Polyphen-2, MutationTaster2, CADD etc. are contradictory. -
