Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2024The c.1472G>A (p.C491Y) alteration is located in exon 10 (coding exon 10) of the MAGI3 gene. This alteration results from a G to A substitution at nucleotide position 1472, causing the cysteine (C) at amino acid position 491 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
