Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.1004G>A (p.R335Q) alteration is located in exon 7 (coding exon 6) of the PARPBP gene. This alteration results from a G to A substitution at nucleotide position 1004, causing the arginine (R) at amino acid position 335 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
