Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.668G>A (p.C223Y) alteration is located in exon 10 (coding exon 10) of the FAIM2 gene. This alteration results from a G to A substitution at nucleotide position 668, causing the cysteine (C) at amino acid position 223 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
