Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.1075A>G (p.K359E) alteration is located in exon 12 (coding exon 11) of the FAM227B gene. This alteration results from a A to G substitution at nucleotide position 1075, causing the lysine (K) at amino acid position 359 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
