not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.3808C>T (p.R1270W) alteration is located in exon 3 (coding exon 2) of the KIAA1462 gene. This alteration results from a C to T substitution at nucleotide position 3808, causing the arginine (R) at amino acid position 1270 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
