Variant summary

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

The NM_001134442.3(ZNF502):c.662G>T(p.Arg221Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000248 in 1,614,060 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. R221Q) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.662G>T (p.R221L) alteration is located in exon 4 (coding exon 2) of the ZNF502 gene. This alteration results from a G to T substitution at nucleotide position 662, causing the arginine (R) at amino acid position 221 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
