not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.257C>A (p.A86D) alteration is located in exon 1 (coding exon 1) of the KIF4B gene. This alteration results from a C to A substitution at nucleotide position 257, causing the alanine (A) at amino acid position 86 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
