Ambry Genetics

May 30, 2024

The c.305G>T (p.R102L) alteration is located in exon 3 (coding exon 2) of the RAB19 gene. This alteration results from a G to T substitution at nucleotide position 305, causing the arginine (R) at amino acid position 102 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
