A novel variant in ALMS1 in a patient with Alstrom syndrome and prenatal diagnosis for the fetus in the family: A case report and literature review.

ABSTRACT: Alström syndrome (AS) is a type of monogenic syndromic ciliopathy disease. The main clinical features of AS include cone‑rod malnutrition, sensorineural hearing loss, metabolic dysfunctions and multiple organ failure, which are caused by mutations of Alström syndrome protein 1 (ALMS1) gene. The current study aimed to identify pathogenic variants in a Chinese patient with AS and to review the relevant literature. Genomic DNA extracted from a 10‑year‑old male with AS was evaluated using a disease‑targeted gene panel. According to the bioinformatics analysis, the current study identified a novel frameshift mutation in exon 8 (c.2988_2989del, p.T996fs) and a rare nonsense mutation in exon 10 (c.9535C>T, p.R3179*) of the ALMS1 gene. Both parents were heterozygous carriers of this gene. To the b
