Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.26G>A (p.R9Q) alteration is located in exon 2 (coding exon 1) of the PARP8 gene. This alteration results from a G to A substitution at nucleotide position 26, causing the arginine (R) at amino acid position 9 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
