CEDNIK syndrome is a rare autosomal recessive syndrome characterized by cerebral dysgenesis, neuropathy, ichthyosis, and keratoderma of which 25 cases from 19 families have been reported to date. It is a progressive neurodegenerative disorder caused by the loss‐of‐function pathogenic variant of the SNAP29 gene encoding a member of the SNARE family of proteins. We describe two female siblings from a Syrian parent‐related family with CEDNIK syndrome due to homozygous pathogenic variant in SNAP29 [c.223delG(p.Val75Serf*28)]. Palmoplantar keratoderma, reported as a cardinal sign in CEDNIK syndrome, was absent in both patients as of the last follow‐up, and one of our patients had a verrucous venous malformation, a finding that has not been previously reported.
