Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BP4_Strong BS1 BS2

The NM_032028.4(TSSK1B):​c.697G>C​(p.Val233Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00286 in 1,614,144 control chromosomes in the GnomAD database, including 96 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V233I) has been classified as Uncertain significance.

Genes affected

TSSK1B (HGNC:14968): (testis specific serine kinase 1B) TSSK1 belongs to a family of serine/threonine kinases highly expressed in testis (Hao et al., 2004 [PubMed 15044604]).[supplied by OMIM, Mar 2008]

MCC (HGNC:6935): (MCC regulator of WNT signaling pathway) This gene is a candidate colorectal tumor suppressor gene that is thought to negatively regulate cell cycle progression. The orthologous gene in the mouse expresses a phosphoprotein associated with the plasma membrane and membrane organelles, and overexpression of the mouse protein inhibits entry into S phase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ENSG00000232633 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002570361).
• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00482 (734/152270) while in subpopulation EAS AF = 0.0424 (219/5164). AF 95% confidence interval is 0.0378. There are 7 homozygotes in GnomAd4. There are 403 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
