Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.997C>G (p.P333A) alteration is located in exon 7 (coding exon 6) of the PARPBP gene. This alteration results from a C to G substitution at nucleotide position 997, causing the proline (P) at amino acid position 333 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
