Genes affected

KDM5A (HGNC:9886): (lysine demethylase 5A) This gene encodes a member of the Jumonji, AT-rich interactive domain 1 (JARID1) histone demethylase protein family. The encoded protein plays a role in gene regulation through the histone code by specifically demethylating lysine 4 of histone H3. The encoded protein interacts with many other proteins, including retinoblastoma protein, and is implicated in the transcriptional regulation of Hox genes and cytokines. This gene may play a role in tumor progression. [provided by RefSeq, Aug 2013]

KDM5A (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 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), KDM5A. . Gene score misZ 2.2471 (greater than the threshold 3.09). Trascript score misZ 3.5946 (greater than threshold 3.09). GenCC has associacion of gene with congenital heart disease.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.829

The c.4856G>A (p.C1619Y) alteration is located in exon 27 (coding exon 27) of the KDM5A gene. This alteration results from a G to A substitution at nucleotide position 4856, causing the cysteine (C) at amino acid position 1619 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
