• chr7-144410186-A-C

Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_001080413.3(NOBOX):​c.42T>G​(p.Gly14=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G14G) has been classified as Benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: NOBOX NM_001080413.3 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -2.32

Genes affected

NOBOX (HGNC:22448): (NOBOX oogenesis homeobox) This homeobox gene encodes a transcription factor that is thought to play a role in oogenesis. In mice, it is essential for folliculogenesis and regulation of oocyte-specific genes. Defects in this gene result in premature ovarian failure type 5.[provided by RefSeq, May 2011]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.98).
• BP7: Synonymous conserved (PhyloP=-2.32 with no splicing effect.
