Variant 15-63601438-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_203373.3(FBXL22):c.496G>A(p.Ala166Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000203 in 1,426,920 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. A166A) has been classified as Likely benign.

Genes affected

FBXL22 (HGNC:27537): (F-box and leucine rich repeat protein 22) This gene encodes a member of the F-box protein family. This F-box protein interacts with S-phase kinase-associated protein 1A and cullin in order to form SCF complexes which function as ubiquitin ligases.[provided by RefSeq, Sep 2010]

The c.496G>A (p.A166T) alteration is located in exon 2 (coding exon 2) of the FBXL22 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the alanine (A) at amino acid position 166 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
