Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2022The c.424C>T (p.R142C) alteration is located in exon 3 (coding exon 3) of the FAM117A gene. This alteration results from a C to T substitution at nucleotide position 424, causing the arginine (R) at amino acid position 142 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
