Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2022The c.1415T>C (p.V472A) alteration is located in exon 6 (coding exon 4) of the HDX gene. This alteration results from a T to C substitution at nucleotide position 1415, causing the valine (V) at amino acid position 472 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
