Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.432G>C (p.Q144H) alteration is located in exon 5 (coding exon 5) of the FAM219B gene. This alteration results from a G to C substitution at nucleotide position 432, causing the glutamine (Q) at amino acid position 144 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
