Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.376G>C (p.A126P) alteration is located in exon 4 (coding exon 4) of the PCBD2 gene. This alteration results from a G to C substitution at nucleotide position 376, causing the alanine (A) at amino acid position 126 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
