Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.1355A>G (p.Y452C) alteration is located in exon 9 (coding exon 9) of the PLBD1 gene. This alteration results from a A to G substitution at nucleotide position 1355, causing the tyrosine (Y) at amino acid position 452 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
