Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 11, 2023The c.838C>G (p.L280V) alteration is located in exon 6 (coding exon 6) of the FAM131A gene. This alteration results from a C to G substitution at nucleotide position 838, causing the leucine (L) at amino acid position 280 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
