Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.902G>A (p.G301D) alteration is located in exon 10 (coding exon 9) of the FARP2 gene. This alteration results from a G to A substitution at nucleotide position 902, causing the glycine (G) at amino acid position 301 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
