Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2024The c.469T>G (p.L157V) alteration is located in exon 3 (coding exon 2) of the FAM222A gene. This alteration results from a T to G substitution at nucleotide position 469, causing the leucine (L) at amino acid position 157 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
