Genes affected

THYN1 (HGNC:29560): (thymocyte nuclear protein 1) This gene encodes a protein that is highly conserved among vertebrates and plant species and may be involved in the induction of apoptosis. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

The c.500G>A (p.R167Q) alteration is located in exon 6 (coding exon 6) of the THYN1 gene. This alteration results from a G to A substitution at nucleotide position 500, causing the arginine (R) at amino acid position 167 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
