Genes affected

MYH10 (HGNC:7568): (myosin heavy chain 10) This gene encodes a member of the myosin superfamily. The protein represents a conventional non-muscle myosin; it should not be confused with the unconventional myosin-10 (MYO10). Myosins are actin-dependent motor proteins with diverse functions including regulation of cytokinesis, cell motility, and cell polarity. Mutations in this gene have been associated with May-Hegglin anomaly and developmental defects in brain and heart. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

NDEL1 (HGNC:17620): (nudE neurodevelopment protein 1 like 1) Enables identical protein binding activity.

Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard

Feb 26, 2024

The heterozygous p.Arg1975His variant in MYH10 was identified in 1 individual with isolated Marcus Gunn jaw-winking synkinesis with congenital ptosis via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Engle lab (https://kirbyneuro.org/EngleLab/). This variant was inherited from the mother of the proband who had isolated congenital ptosis without Marcus Gunn jaw-winking synkinesis. While this gene is still lacking sufficient evidence to establish a gene-disease association, we believe this is a possible novel gene candidate for Marcus Gunn jaw-winking syndrome. Given the limited information about this gene-disease relationship, the significance of the p.Arg1975His variant is uncertain. If you have any additional information about functional evidence or other individuals with this phenotype that also have variants in MYH10 we encourage you to reach out to the Engle Lab (elizabeth.engle@childrens.harvard.edu). -
