Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2024The c.79G>A (p.V27M) alteration is located in exon 1 (coding exon 1) of the MXRA7 gene. This alteration results from a G to A substitution at nucleotide position 79, causing the valine (V) at amino acid position 27 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
