Genes affected

LARP1 (HGNC:29531): (La ribonucleoprotein 1, translational regulator) Enables eukaryotic initiation factor 4E binding activity; nucleic acid binding activity; and ribosomal small subunit binding activity. Involved in several processes, including TORC1 signaling; cellular response to rapamycin; and posttranscriptional regulation of gene expression. Located in cytoplasmic stress granule. Colocalizes with TORC1 complex and polysomal ribosome. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.896C>T (p.T299M) alteration is located in exon 7 (coding exon 7) of the LARP1 gene. This alteration results from a C to T substitution at nucleotide position 896, causing the threonine (T) at amino acid position 299 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
