Variant 1-32593418-C-T 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_001040441.3(ZBTB8A):c.487C>T(p.Arg163Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,461,730 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/19 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. R163H) has been classified as Likely benign.

Dec 15, 2023

The c.487C>T (p.R163C) alteration is located in exon 3 (coding exon 1) of the ZBTB8A gene. This alteration results from a C to T substitution at nucleotide position 487, causing the arginine (R) at amino acid position 163 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
