not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 12, 2023The c.1103C>A (p.A368E) alteration is located in exon 12 (coding exon 11) of the FAM227B gene. This alteration results from a C to A substitution at nucleotide position 1103, causing the alanine (A) at amino acid position 368 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
