Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.1909C>G (p.P637A) alteration is located in exon 15 (coding exon 14) of the KANSL3 gene. This alteration results from a C to G substitution at nucleotide position 1909, causing the proline (P) at amino acid position 637 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
