Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 16, 2024The c.1282C>T (p.R428W) alteration is located in exon 13 (coding exon 13) of the MAU2 gene. This alteration results from a C to T substitution at nucleotide position 1282, causing the arginine (R) at amino acid position 428 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
