Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The ENST00000339296.10(ZNF621):​c.733C>A​(p.Arg245Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 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. R245C) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)

The c.733C>A (p.R245S) alteration is located in exon 5 (coding exon 4) of the ZNF621 gene. This alteration results from a C to A substitution at nucleotide position 733, causing the arginine (R) at amino acid position 245 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
