Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.820A>C (p.S274R) alteration is located in exon 6 (coding exon 5) of the PARPBP gene. This alteration results from a A to C substitution at nucleotide position 820, causing the serine (S) at amino acid position 274 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
