Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.253C>T (p.R85W) alteration is located in exon 4 (coding exon 2) of the FAM118A gene. This alteration results from a C to T substitution at nucleotide position 253, causing the arginine (R) at amino acid position 85 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
