Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2021The c.241A>G (p.M81V) 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 241, causing the methionine (M) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
