Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.571G>A (p.V191I) alteration is located in exon 4 (coding exon 4) of the RASGEF1A gene. This alteration results from a G to A substitution at nucleotide position 571, causing the valine (V) at amino acid position 191 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
