KIF1A is a molecular motor for membrane-bound cargo important to the development and survival of sensory neurons. KIF1A dysfunction has been associated with several Mendelian disorders with a spectrum of overlapping phenotypes, ranging from spastic paraplegia to intellectual disability. We present a novel pathogenic in-frame deletion in the KIF1A molecular motor domain inherited by two affected siblings from an unaffected mother with apparent germline mosaicism. We identified eight additional cases with heterozygous, pathogenic KIF1A variants ascertained from a local data lake. Our data provide evidence for the expansion of KIF1A-associated phenotypes to include hip subluxation and dystonia as well as phenotypes observed in only a single case: gelastic cataplexy, coxa valga, and double collecting system. We review the literature and suggest that KIF1A dysfunction is better understood as ...

El síndrome de Lynch (SL), es un síndrome genético con patrón de herencia autosómico dominante, que predispone el desarrollo de cáncer colorrectal y neoplasias extracolónicas, debido a la mutación germinal en alguno de los genes reparadores de los errores de la replicación del ADN (MLH1, MSH2, MSH6 o PMS2). El Síndrome de Muir-Torre (SMT), es una variante fenotípica del SL que predispone además a desarrollar tumores de glándulas sebáceas y queratoacantomas. Presentamos el caso de dos pacientes con SMT, con más de una neoplasia relacionada al SL, lesiones cutáneas, antecedentes familiares de cáncer y estudios de inestabilidad de microsatélites e inmunohistoquímica.
