Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.1465G>A (p.A489T) 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 1465, causing the alanine (A) at amino acid position 489 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
