Genes affected

EIPR1 (HGNC:12383): (EARP complex and GARP complex interacting protein 1) This gene has been reported in PMID 9403053 as one of several tumor-suppressing subtransferable fragments located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer. Alignment of this gene to genomic sequence data suggests that this gene resides on chromosome 2 rather than chromosome 11. [provided by RefSeq, Dec 2008]

The c.1048G>A (p.V350I) alteration is located in exon 9 (coding exon 9) of the TSSC1 gene. This alteration results from a G to A substitution at nucleotide position 1048, causing the valine (V) at amino acid position 350 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
