Genes affected

RAB4A (HGNC:9781): (RAB4A, member RAS oncogene family) This gene is a member of the largest group in the Ras superfamily of small GTPases, which regulate membrane trafficking. The encoded protein is associated with early endosomes and is involved in their sorting and recycling. The protein also plays a role in regulating the recycling of receptors from endosomes to the plasma membrane. Alternatively spliced transcript variants have been observed for this gene.

Ambry Genetics

May 12, 2024

The c.172G>T (p.G58C) alteration is located in exon 3 (coding exon 3) of the RAB4A gene. This alteration results from a G to T substitution at nucleotide position 172, causing the glycine (G) at amino acid position 58 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
