Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.52G>C (p.E18Q) alteration is located in exon 3 (coding exon 1) of the KIAA1456 gene. This alteration results from a G to C substitution at nucleotide position 52, causing the glutamic acid (E) at amino acid position 18 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
