Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.1121C>G (p.A374G) alteration is located in exon 8 (coding exon 8) of the MAGI3 gene. This alteration results from a C to G substitution at nucleotide position 1121, causing the alanine (A) at amino acid position 374 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
