Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2024The c.3809G>C (p.R1270P) alteration is located in exon 3 (coding exon 2) of the KIAA1462 gene. This alteration results from a G to C substitution at nucleotide position 3809, causing the arginine (R) at amino acid position 1270 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
