Genes affected
APLF (HGNC:28724): (aprataxin and PNKP like factor) Enables DNA-(apurinic or apyrimidinic site) endonuclease activity; nuclease activity; and nucleotide binding activity. Involved in double-strand break repair via nonhomologous end joining and single strand break repair. Acts upstream of or within positive regulation of DNA ligation. Located in nucleoplasm. Is active in site of double-strand break. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2022The c.524A>G (p.Q175R) alteration is located in exon 5 (coding exon 5) of the APLF gene. This alteration results from a A to G substitution at nucleotide position 524, causing the glutamine (Q) at amino acid position 175 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
