Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.830G>T (p.C277F) alteration is located in exon 2 (coding exon 1) of the SLFN12 gene. This alteration results from a G to T substitution at nucleotide position 830, causing the cysteine (C) at amino acid position 277 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
