Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 05, 2023The c.389T>C (p.V130A) alteration is located in exon 5 (coding exon 3) of the KIAA1456 gene. This alteration results from a T to C substitution at nucleotide position 389, causing the valine (V) at amino acid position 130 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
