Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2024The c.54C>G (p.I18M) alteration is located in exon 2 (coding exon 1) of the PARP8 gene. This alteration results from a C to G substitution at nucleotide position 54, causing the isoleucine (I) at amino acid position 18 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
