Provisionally associated with ?Deafness, autosomal recessive 97 MIM#616705 in OMIM. 2 cases reported:
PMID: 25941349 - Mujtaba et al 2015 - report a large consanguineous Pakistani family with some members affected by hearing loss. They identified, through genome-wide homozygosity mapping and then whole exome sequencing, a homozygous missense variant located in MET (NM_000245.2), c.2521T>G (p.F841V) that segregates with hearing loss in 9 affected individuals.
PMID: 27717089 - Alabdullatif et al 2017 - from a review of clinical and molecular data for 227 individuals from a highly consanguineous population who underwent a combined (CGH+SNP) CMA test, they report 2 brothers with hearing loss and arthrogryposis in which a homozygous variant c.3557T>G (p.F1186C) in MET was identified through WES after a region of homozygosity was identified. The first cousin parents were both heterozygous for this variant. They suggest that the arthrogryposis could be a variable feature of the disease or be caused by a second recessive disease not detected in this study.
