Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.52T>G (p.F18V) alteration is located in exon 4 (coding exon 2) of the FAM118A gene. This alteration results from a T to G substitution at nucleotide position 52, causing the phenylalanine (F) at amino acid position 18 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
