Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.763A>C (p.S255R) alteration is located in exon 2 (coding exon 1) of the SLFN12 gene. This alteration results from a A to C substitution at nucleotide position 763, causing the serine (S) at amino acid position 255 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
