Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.178C>G (p.P60A) alteration is located in exon 3 (coding exon 2) of the MON1B gene. This alteration results from a C to G substitution at nucleotide position 178, causing the proline (P) at amino acid position 60 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
