Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2024The c.524C>T (p.A175V) alteration is located in exon 1 (coding exon 1) of the KLHL42 gene. This alteration results from a C to T substitution at nucleotide position 524, causing the alanine (A) at amino acid position 175 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
