Variant summary

Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM2 PM5 PP3_Moderate PP5_Moderate

The NM_001009999.3(KDM1A):​c.1207G>A​(p.Glu403Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E403A) has been classified as Likely pathogenic.

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.

ACMG classification

Our verdict: Likely_pathogenic. The variant received 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr1-23068567-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1691768.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.876
• PP5: Variant 1-23068566-G-A is Pathogenic according to our data. Variant chr1-23068566-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 218912.Status of the report is criteria_provided_single_submitter, 1 stars.
