Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.3862T>A (p.L1288M) alteration is located in exon 18 (coding exon 17) of the FAM135B gene. This alteration results from a T to A substitution at nucleotide position 3862, causing the leucine (L) at amino acid position 1288 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
