Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.619G>A (p.G207S) alteration is located in exon 4 (coding exon 2) of the FAM222B gene. This alteration results from a G to A substitution at nucleotide position 619, causing the glycine (G) at amino acid position 207 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
