Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.356G>A (p.R119K) alteration is located in exon 5 (coding exon 5) of the IQCE gene. This alteration results from a G to A substitution at nucleotide position 356, causing the arginine (R) at amino acid position 119 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

PreventionGenetics, part of Exact Sciences

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The IQCE c.356G>A variant is predicted to result in the amino acid substitution p.Arg119Lys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
