Genes affected

DENND4A (HGNC:24321): (DENN domain containing 4A) This gene encodes a DENN domain-containing protein that may function as a guanine nucleotide exchange factor that specifically activates ras-related protein Rab-10. This protein also contains a interferon stimulated response element-binding domain and may be involved in regulating the v-myc avian myelocytomatosis viral (MYC) oncogene. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 8. [provided by RefSeq, Mar 2016]

The c.4852G>C (p.A1618P) alteration is located in exon 28 (coding exon 26) of the DENND4A gene. This alteration results from a G to C substitution at nucleotide position 4852, causing the alanine (A) at amino acid position 1618 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
