Here we describe a new clinically distinguishable recessive syndrome in 12 families with cerebellar atrophy together with ataxia, coarsened facial features and intellectual disability, due to truncating mutations in the sorting nexin gene SNX14, encoding a ubiquitously expressed modular PX domain-containing sorting factor. We found SNX14 localized to lysosomes and associated with phosphatidylinositol (3,5)-bisphosphate, a key component of late endosomes/lysosomes. Patient-derived cells showed engorged lysosomes and a slower autophagosome clearance rate upon autophagy induction by starvation. Zebrafish morphants for snx14 showed dramatic loss of cerebellar parenchyma, accumulation of autophagosomes and activation of apoptosis. Our results characterize a unique ataxia syndrome due to biallelic SNX14 mutations leading to lysosome-autophagosome dysfunction.</subfield> </datafield> <datafield tag="650" ind1="1" ind2="7"> <subfield code="2">opendefinition.org</subfield> <subfield code="a">cc-by</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Hop Necker Enfants Malad, INSERM, Inst Imagine, U1163, Paris, France</subfield> <subfield code="a">Cantagrel, Vincent</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Natl Res Ctr, Dept Clin Genet, Human Genet & Genome Res Div, Cairo, Egypt</subfield> <subfield code="a">Zaki, Maha S.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">United Arab Emirates Univ, Dept Pediat, Coll Med & Hlth Sci, Abu Dhabi, U Arab Emirates</subfield> <subfield code="a">Al-Gazali, Lihadh</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Wang, Xin</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Rosti, Rasim Ozgur</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Dikoglu, Esra</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Gelot, Antoinette Bernabe</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Rosti, Basak</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Vaux, Keith K.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Scott, Eric M.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Silhavy, Jennifer L.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Schroth, Jana</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Copeland, Brett</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="a">Schaffer, Ashleigh E.</subfield> </datafield> <datafield tag="700" ind1=" " ind2=" "> <subfield code="u">Univ Calif San Diego, Dept Cellular & Mol Med, La Jolla, CA 92093 USA</subfield> <subfield code="a">Gordts, Philip L.
