Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.780G>T (p.L260F) alteration is located in exon 7 (coding exon 7) of the FAM131B gene. This alteration results from a G to T substitution at nucleotide position 780, causing the leucine (L) at amino acid position 260 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
