Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 07, 2023 | The c.718A>G (p.S240G) alteration is located in exon 1 (coding exon 1) of the XKR4 gene. This alteration results from a A to G substitution at nucleotide position 718, causing the serine (S) at amino acid position 240 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
