Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2024The c.49C>G (p.R17G) alteration is located in exon 1 (coding exon 1) of the MPZL1 gene. This alteration results from a C to G substitution at nucleotide position 49, causing the arginine (R) at amino acid position 17 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
