Variant rs569851088 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_152393.4(KLHL40):c.1850G>A(p.Cys617Tyr) variant causes a missense change. The variant allele was found at a frequency of 0.0000343 in 1,601,210 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. C617R) has been classified as Benign.

Genes affected

KLHL40 (HGNC:30372): (kelch like family member 40) This gene encodes a protein containing a BACK domain, a BTB/POZ domain, and 5 Kelch repeats, however, its exact function is not known. The gene and the multi-domain protein structure are conserved across different taxa, including primates, rodents, chicken and zebrafish. [provided by RefSeq, Dec 2012]

The c.1850G>A (p.C617Y) alteration is located in exon 6 (coding exon 6) of the KLHL40 gene. This alteration results from a G to A substitution at nucleotide position 1850, causing the cysteine (C) at amino acid position 617 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
