Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2021The c.2032G>T (p.V678L) alteration is located in exon 11 (coding exon 9) of the HDX gene. This alteration results from a G to T substitution at nucleotide position 2032, causing the valine (V) at amino acid position 678 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
