Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 12, 2024The c.788A>G (p.N263S) alteration is located in exon 9 (coding exon 8) of the FARP2 gene. This alteration results from a A to G substitution at nucleotide position 788, causing the asparagine (N) at amino acid position 263 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
