Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.202G>A (p.D68N) alteration is located in exon 3 (coding exon 3) of the KIF19 gene. This alteration results from a G to A substitution at nucleotide position 202, causing the aspartic acid (D) at amino acid position 68 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
