PMID: 29276006 - White et al 2018 - report 2 families with biallelic variants in NXN that co-segregate with Robinow syndrome. Family 1 - the proband has a several phenotypic features including the limb phenotypes of brachydactyly and mesomelic shortening, fifth finger brachydactyly and clinodactyly and broad thumbs and great toes. A homozygous stopgain variant in NXN c.625C>T [p.Arg209∗] was found to be inherited from consanguineous parents. Family 2 - although the overall length of the proband was in the normal range, she had the appearance of short limbs and she had an unusual pattern of hand and foot development with brachydactyly and incurving of her fingers towards the middle finger. There was a wide sandal gap and the same clinodactyly pattern in her feet. Other craniofacial features were also present. A younger sibling was remarkably alike in terms of facial features and limb patterning. The siblings shared compound heterozygous biallelic variants in NXN: a maternally inherited in-frame 3-bp deletion (c.1234_1236del [p.Glu412del]) and a paternally inherited intragenic 84-kb deletion that encompasses the entire first exon chr17:g.805043::GAGG…..AATG::889090).
