Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.125G>A (p.G42D) alteration is located in exon 2 (coding exon 2) of the MPZL3 gene. This alteration results from a G to A substitution at nucleotide position 125, causing the glycine (G) at amino acid position 42 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
