not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.1496G>A (p.R499H) alteration is located in exon 13 (coding exon 12) of the KANSL3 gene. This alteration results from a G to A substitution at nucleotide position 1496, causing the arginine (R) at amino acid position 499 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
