Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.634A>G (p.T212A) alteration is located in exon 5 (coding exon 5) of the PLBD1 gene. This alteration results from a A to G substitution at nucleotide position 634, causing the threonine (T) at amino acid position 212 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
