Genes affected

KDM1A (HGNC:29079): (lysine demethylase 1A) This gene encodes a nuclear protein containing a SWIRM domain, a FAD-binding motif, and an amine oxidase domain. This protein is a component of several histone deacetylase complexes, though it silences genes by functioning as a histone demethylase. Alternative splicing results in multiple transcript variants.

KDM1A (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_001009999.3
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KDM1A. . Gene score misZ 4.6784 (greater than the threshold 3.09). Trascript score misZ 3.7869 (greater than threshold 3.09). GenCC has associacion of gene with palatal anomalies-widely spaced teeth-facial dysmorphism-developmental delay syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.862
