Genes affected

RAB38 (HGNC:9776): (RAB38, member RAS oncogene family) Enables several functions, including AP-1 adaptor complex binding activity; AP-3 adaptor complex binding activity; and BLOC-2 complex binding activity. Involved in several processes, including endosome to melanosome transport; melanosome assembly; and phagosome acidification. Located in several cellular components, including cytoplasmic vesicle; lysosome; and mitochondria-associated endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 15, 2023

The c.491T>C (p.I164T) alteration is located in exon 3 (coding exon 3) of the RAB38 gene. This alteration results from a T to C substitution at nucleotide position 491, causing the isoleucine (I) at amino acid position 164 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
