Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.542G>A (p.R181Q) alteration is located in exon 7 (coding exon 6) of the FARP2 gene. This alteration results from a G to A substitution at nucleotide position 542, causing the arginine (R) at amino acid position 181 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
