Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.175G>A (p.V59I) alteration is located in exon 4 (coding exon 2) of the FAM118A gene. This alteration results from a G to A substitution at nucleotide position 175, causing the valine (V) at amino acid position 59 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
