Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.1457C>T (p.A486V) alteration is located in exon 3 (coding exon 3) of the XKR6 gene. This alteration results from a C to T substitution at nucleotide position 1457, causing the alanine (A) at amino acid position 486 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
