Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.587C>G (p.T196S) alteration is located in exon 3 (coding exon 2) of the MUC22 gene. This alteration results from a C to G substitution at nucleotide position 587, causing the threonine (T) at amino acid position 196 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
