Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.1064T>G (p.V355G) alteration is located in exon 4 (coding exon 2) of the HDX gene. This alteration results from a T to G substitution at nucleotide position 1064, causing the valine (V) at amino acid position 355 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
