Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.80G>A (p.S27N) alteration is located in exon 2 (coding exon 1) of the FARP2 gene. This alteration results from a G to A substitution at nucleotide position 80, causing the serine (S) at amino acid position 27 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
