Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 26, 2023The c.1318A>G (p.N440D) alteration is located in exon 10 (coding exon 10) of the MXRA8 gene. This alteration results from a A to G substitution at nucleotide position 1318, causing the asparagine (N) at amino acid position 440 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
