Genes affected
GARIN4 (HGNC:26541): (golgi associated RAB2 interactor family member 4) This gene encodes a protein that interacts with the Rab2B small GTPase and may be important for integrity of the Golgi body. A knockdown of this gene induces fragmentation of the Golgi, similar to the effect seen with a knockdown of the Rab2B small GTPase. The encoded protein has an N-terminal Rab-binding domain specific for Rab2B. [provided by RefSeq, Feb 2017]

The c.311C>T (p.A104V) alteration is located in exon 1 (coding exon 1) of the FAM71A gene. This alteration results from a C to T substitution at nucleotide position 311, causing the alanine (A) at amino acid position 104 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
