Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.850G>A (p.D284N) alteration is located in exon 6 (coding exon 6) of the XKR5 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the aspartic acid (D) at amino acid position 284 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
