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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.344C>G (p.P115R) alteration is located in exon 2 (coding exon 2) of the RAB38 gene. This alteration results from a C to G substitution at nucleotide position 344, causing the proline (P) at amino acid position 115 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
