Variant 2-96608953-G-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_001115016.3(KANSL3):c.1495C>T(p.Arg499Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000173 in 1,564,532 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R499H) has been classified as Uncertain significance.

Ambry Genetics

Feb 27, 2023

The c.1495C>T (p.R499C) alteration is located in exon 13 (coding exon 12) of the KANSL3 gene. This alteration results from a C to T substitution at nucleotide position 1495, causing the arginine (R) at amino acid position 499 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
