Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.149C>A (p.T50N) alteration is located in exon 3 (coding exon 3) of the FAM131B gene. This alteration results from a C to A substitution at nucleotide position 149, causing the threonine (T) at amino acid position 50 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
