Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2024The c.242T>C (p.V81A) alteration is located in exon 4 (coding exon 2) of the FAM118A gene. This alteration results from a T to C substitution at nucleotide position 242, causing the valine (V) at amino acid position 81 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
