Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.641A>G (p.E214G) alteration is located in exon 3 (coding exon 2) of the MUC22 gene. This alteration results from a A to G substitution at nucleotide position 641, causing the glutamic acid (E) at amino acid position 214 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
