Variant 1-23019756-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4_ModerateBS2

The NM_001009999.3(KDM1A):c.160G>A(p.Ala54Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000438 in 1,346,530 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A54V) has been classified as Uncertain significance.

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.

A heterozygous missense variant was identified, NM_001009999.2(KDM1A):c.160G>A in exon 1 of 21 of the KDM1A gene. This substitution is predicted to create a minor amino acid change from alanine to threonine at position 54 of the protein, NP_001009999.1(KDM1A):p.(Ala54Thr). The alanine at this position has low conservation (100 vertebrates, UCSC), and is not situated in a known functional domain (PDB, NCBI). In silico software predictions of the pathogenicity of this variant are conflicting (PolyPhen, SIFT, CADD, MutationTaster). The variant is not present in the gnomAD population database, however low coverage was observed in this region. The variant has not previously been reported in clinical cases. Based on information available at the time of curation, this variant has been classified as a VARIANT of UNCERTAIN SIGNIFICANCE (VUS) with LOW CLINICAL RELEVANCE. -
