Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.572C>T (p.P191L) alteration is located in exon 7 (coding exon 6) of the FARP2 gene. This alteration results from a C to T substitution at nucleotide position 572, causing the proline (P) at amino acid position 191 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
