Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 29, 2023The c.1561C>T (p.R521C) alteration is located in exon 11 (coding exon 11) of the PLBD1 gene. This alteration results from a C to T substitution at nucleotide position 1561, causing the arginine (R) at amino acid position 521 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
