Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2023The c.2618G>A (p.R873H) alteration is located in exon 21 (coding exon 20) of the KANSL3 gene. This alteration results from a G to A substitution at nucleotide position 2618, causing the arginine (R) at amino acid position 873 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
