Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2023The c.148A>G (p.I50V) alteration is located in exon 4 (coding exon 3) of the MUM1 gene. This alteration results from a A to G substitution at nucleotide position 148, causing the isoleucine (I) at amino acid position 50 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
