Genes affected

SNHG1 (HGNC:32688): (small nucleolar RNA host gene 1) This locus represents a small nucleolar RNA host gene that produces multiple alternatively spliced long non-coding RNAs. This gene is upregulated in cancers and is thought to act as promoter of cell proliferation. This transcript negatively regulates tumor suppressor genes such as tumor protein p53. Expression of this locus may be a marker of tumor progression. [provided by RefSeq, Dec 2017]

STX5-DT (HGNC:55488): (STX5 divergent transcript)

SLC3A2 (HGNC:11026): (solute carrier family 3 member 2) This gene is a member of the solute carrier family and encodes a cell surface, transmembrane protein. The protein exists as the heavy chain of a heterodimer, covalently bound through di-sulfide bonds to one of several possible light chains. The encoded transporter plays a role in regulation of intracellular calcium levels and transports L-type amino acids. Alternatively spliced transcript variants, encoding different isoforms, have been characterized. [provided by RefSeq, Nov 2010]

SNORD25 (HGNC:10147): (small nucleolar RNA, C/D box 25)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
