Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2023The c.1322G>A (p.R441Q) alteration is located in exon 3 (coding exon 3) of the XKR6 gene. This alteration results from a G to A substitution at nucleotide position 1322, causing the arginine (R) at amino acid position 441 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
