Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.2216C>T (p.T739I) alteration is located in exon 18 (coding exon 17) of the KANSL3 gene. This alteration results from a C to T substitution at nucleotide position 2216, causing the threonine (T) at amino acid position 739 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
