Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.305G>C (p.W102S) alteration is located in exon 3 (coding exon 3) of the MPZL3 gene. This alteration results from a G to C substitution at nucleotide position 305, causing the tryptophan (W) at amino acid position 102 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
