Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 20, 2024The c.320A>G (p.H107R) alteration is located in exon 4 (coding exon 4) of the PCBD2 gene. This alteration results from a A to G substitution at nucleotide position 320, causing the histidine (H) at amino acid position 107 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
