Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 29, 2024The c.257C>G (p.A86G) 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 257, causing the alanine (A) at amino acid position 86 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
