Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2022The c.755A>G (p.N252S) alteration is located in exon 5 (coding exon 5) of the KIAA1217 gene. This alteration results from a A to G substitution at nucleotide position 755, causing the asparagine (N) at amino acid position 252 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
