Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.262T>A (p.Y88N) alteration is located in exon 3 (coding exon 2) of the PARPBP gene. This alteration results from a T to A substitution at nucleotide position 262, causing the tyrosine (Y) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
