Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.524C>A (p.T175N) alteration is located in exon 3 (coding exon 2) of the MUC22 gene. This alteration results from a C to A substitution at nucleotide position 524, causing the threonine (T) at amino acid position 175 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
