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.258G>T (p.M86I) alteration is located in exon 1 (coding exon 1) of the FAM71A gene. This alteration results from a G to T substitution at nucleotide position 258, causing the methionine (M) at amino acid position 86 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
