Genes affected

ARHGAP11A (HGNC:15783): (Rho GTPase activating protein 11A) This gene encodes a member of the Rho GTPase activating protein family. In response to DNA damage, the encoded protein interacts with the p53 tumor suppressor protein and stimulates its tetramerization, which results in cell-cycle arrest and apoptosis. A chromosomal deletion that includes this gene is one cause of Prader-Willi syndrome, and an intronic variant of this gene may be associated with sleep duration in children. This gene is highly expressed in colon cancers and in a human basal-like breast cancer cell line. This gene also produces a ARHGAP11A-SCG5 readthrough transcript and ARHGAP11A-SCG5 protein.

ARHGAP11A-SCG5 (HGNC:56310): (ARHGAP11A-SCG5 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring ARHGAP11A (Rho GTPase activating protein 11A) and SCG5 (secretogranin V) genes on chromosome 15q13.3. The readthrough transcript encodes a fusion protein that shares sequence identity with both the ARHGAP11A and SCG5 gene products. [provided by RefSeq, Feb 2019]

The c.335C>T (p.A112V) alteration is located in exon 4 (coding exon 4) of the ARHGAP11A gene. This alteration results from a C to T substitution at nucleotide position 335, causing the alanine (A) at amino acid position 112 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
