Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.19G>T (p.A7S) alteration is located in exon 1 (coding exon 1) of the MPZL3 gene. This alteration results from a G to T substitution at nucleotide position 19, causing the alanine (A) at amino acid position 7 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
