Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.268G>T (p.A90S) alteration is located in exon 2 (coding exon 2) of the FAM219B gene. This alteration results from a G to T substitution at nucleotide position 268, causing the alanine (A) at amino acid position 90 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
