Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.551G>A (p.S184N) alteration is located in exon 4 (coding exon 4) of the MPZL1 gene. This alteration results from a G to A substitution at nucleotide position 551, causing the serine (S) at amino acid position 184 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
