Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.757G>A (p.V253I) alteration is located in exon 8 (coding exon 7) of the FARP2 gene. This alteration results from a G to A substitution at nucleotide position 757, causing the valine (V) at amino acid position 253 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
