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 Benign. Variant got -19 ACMG points.

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=0.009864181).

BP6

Variant 22-30942209-C-A is Benign according to our data. Variant chr22-30942209-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 475595.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000256 (39/152356) while in subpopulation EAS AF= 0.00636 (33/5192). AF 95% confidence interval is 0.00465. There are 0 homozygotes in gnomad4. There are 24 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 39 AD gene.

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
