Genes affected

PHLDA2 (HGNC:12385): (pleckstrin homology like domain family A member 2) This gene is located in a cluster of imprinted genes on chromosome 11p15.5, which is considered to be an important tumor suppressor gene region. Alterations in this region may be associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocortical carcinoma, and lung, ovarian, and breast cancer. This gene has been shown to be imprinted, with preferential expression from the maternal allele in placenta and liver. [provided by RefSeq, Oct 2010]

The c.231C>G (p.H77Q) alteration is located in exon 1 (coding exon 1) of the PHLDA2 gene. This alteration results from a C to G substitution at nucleotide position 231, causing the histidine (H) at amino acid position 77 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
