Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023The c.1231G>A (p.D411N) alteration is located in exon 3 (coding exon 3) of the XKR7 gene. This alteration results from a G to A substitution at nucleotide position 1231, causing the aspartic acid (D) at amino acid position 411 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
