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]

Charcot-Marie-Tooth disease axonal type 2Z Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 31, 2021 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with MORC2-related disease. This variant is present in population databases (rs770774096, ExAC 0.05%). This sequence change replaces proline with threonine at codon 521 of the MORC2 protein (p.Pro521Thr). The proline residue is moderately conserved and there is a small physicochemical difference between proline and threonine. - |
