not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2024The c.1315T>A (p.L439M) alteration is located in exon 11 (coding exon 11) of the KIAA0907 gene. This alteration results from a T to A substitution at nucleotide position 1315, causing the leucine (L) at amino acid position 439 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
