Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2023The c.763C>G (p.L255V) alteration is located in exon 1 (coding exon 1) of the KLHL42 gene. This alteration results from a C to G substitution at nucleotide position 763, causing the leucine (L) at amino acid position 255 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
