Variant summary

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

The NM_001143768.2(ZNF438):c.2468C>G(p.Ser823Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,682 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. S823A) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.2468C>G (p.S823C) alteration is located in exon 8 (coding exon 3) of the ZNF438 gene. This alteration results from a C to G substitution at nucleotide position 2468, causing the serine (S) at amino acid position 823 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
