Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The NM_001303256.3(MORC2):​c.1768C>G​(p.Leu590Val) variant causes a missense 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. 14/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. L590L) has been classified as Likely benign.

Genes affected
MORC2 (HGNC:23573): (MORC family CW-type zinc finger 2) This gene encodes a member of the Microrchidia (MORC) protein superfamily. The encoded protein is known to regulate the condensation of heterochromatin in response to DNA damage and play a role in repressing transcription. The protein has been found to regulate the activity of ATP citrate lyase via specific interaction with this enzyme in the cytosol of lipogenic breast cancer cells. The protein also plays a role in lipogenesis and adipocyte differentiation. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Feb 2016]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MORC2. . Gene score misZ 3.2251 (greater than the threshold 3.09). Trascript score misZ 4.4393 (greater than threshold 3.09). GenCC has associacion of gene with Leigh syndrome, Charcot-Marie-Tooth disease axonal type 2Z, developmental delay, impaired growth, dysmorphic facies, and axonal neuropathy.
BP4
Computational evidence support a benign effect (MetaRNN=0.07682523).
