Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2022The c.1270G>C (p.V424L) alteration is located in exon 5 (coding exon 3) of the HDX gene. This alteration results from a G to C substitution at nucleotide position 1270, causing the valine (V) at amino acid position 424 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
