Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.134G>C (p.G45A) alteration is located in exon 2 (coding exon 2) of the MPZL3 gene. This alteration results from a G to C substitution at nucleotide position 134, causing the glycine (G) at amino acid position 45 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
