Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2024The c.770T>C (p.L257S) alteration is located in exon 11 (coding exon 8) of the FAM208B gene. This alteration results from a T to C substitution at nucleotide position 770, causing the leucine (L) at amino acid position 257 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
