Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2023The c.776C>T (p.P259L) alteration is located in exon 5 (coding exon 5) of the XKR5 gene. This alteration results from a C to T substitution at nucleotide position 776, causing the proline (P) at amino acid position 259 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
