Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 12, 2024The c.554C>T (p.T185M) alteration is located in exon 6 (coding exon 5) of the FAM168B gene. This alteration results from a C to T substitution at nucleotide position 554, causing the threonine (T) at amino acid position 185 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
