Genes affected
RASSF2 (HGNC:9883): (Ras association domain family member 2) This gene encodes a protein that contains a Ras association domain. Similar to its cattle and sheep counterparts, this gene is located near the prion gene. Two alternatively spliced transcripts encoding the same isoform have been reported.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.200G>A (p.R67H) alteration is located in exon 5 (coding exon 3) of the RASSF2 gene. This alteration results from a G to A substitution at nucleotide position 200, causing the arginine (R) at amino acid position 67 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
