Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2023The c.284C>A (p.T95K) 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 284, causing the threonine (T) at amino acid position 95 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
