Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.14C>A (p.A5D) alteration is located in exon 1 (coding exon 1) of the MPZL1 gene. This alteration results from a C to A substitution at nucleotide position 14, causing the alanine (A) at amino acid position 5 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
