Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.944G>T (p.G315V) alteration is located in exon 11 (coding exon 10) of the FAM227B gene. This alteration results from a G to T substitution at nucleotide position 944, causing the glycine (G) at amino acid position 315 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
