Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.1702G>A (p.V568M) alteration is located in exon 1 (coding exon 1) of the KLHL34 gene. This alteration results from a G to A substitution at nucleotide position 1702, causing the valine (V) at amino acid position 568 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
