Variant 20-23364576-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_022482.5(GZF1):c.193C>A(p.Leu65Ile) variant causes a missense change. The variant allele was found at a frequency of 0.0000041 in 1,461,868 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. L65R) has been classified as Uncertain significance.

The c.193C>A (p.L65I) alteration is located in exon 1 (coding exon 1) of the GZF1 gene. This alteration results from a C to A substitution at nucleotide position 193, causing the leucine (L) at amino acid position 65 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
