Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.295C>T (p.L99F) alteration is located in exon 3 (coding exon 2) of the KANSL2 gene. This alteration results from a C to T substitution at nucleotide position 295, causing the leucine (L) at amino acid position 99 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
