Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.481G>A (p.G161S) alteration is located in exon 4 (coding exon 4) of the FAM131A gene. This alteration results from a G to A substitution at nucleotide position 481, causing the glycine (G) at amino acid position 161 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
