Variant summary

Our verdict is Benign. The variant received -15 ACMG points: 1P and 16B. PP3BP4_StrongBP6_Very_StrongBS2

The NM_001101362.3(KBTBD13):c.794G>A(p.Gly265Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0121 in 1,582,006 control chromosomes in the GnomAD database, including 169 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G265S) has been classified as Uncertain significance.

Genes affected

KBTBD13 (HGNC:37227): (kelch repeat and BTB domain containing 13) The gene belongs to a family of genes encoding proteins containing a BTB domain and several kelch repeats. The BTB domain functions as a protein-protein interaction module, which includes an ability to self-associate or to interact with non-BTB domain-containing proteins. The kelch motif typically occurs in groups of five to seven repeats, and has been found in proteins with diverse functions. Known functions of these family members include transcription regulation, ion channel tetramerization and gating, protein ubiquitination or degradation, and cytoskeleton regulation. The exact function of this family member has yet to be determined. [provided by RefSeq, Jun 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -15 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 10: AlphaMissense, BayesDel_noAF, Cadd, Eigen, MutationAssessor, phyloP100way_vertebrate, PrimateAI, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.015187234).

BP6

Variant 15-65077609-G-A is Benign according to our data. Variant chr15-65077609-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 129310.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS2

High AC in GnomAd4 at 1384 AD,Unknown gene.
