Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1370G>A (p.G457E) 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 1370, causing the glycine (G) at amino acid position 457 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
