Genes affected
LARP1B (HGNC:24704): (La ribonucleoprotein 1B) This gene encodes a protein containing domains found in the La related protein of Drosophila melanogaster. La motif-containing proteins are thought to be RNA-binding proteins, where the La motif and adjacent amino acids fold into an RNA recognition motif. The La motif is also found in proteins unrelated to the La protein. Alternative splicing has been observed at this locus and multiple variants, encoding distinct isoforms, are described. Additional splice variation has been identified but the full-length nature of these transcripts has not been determined. [provided by RefSeq, Jun 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.997C>G (p.P333A) alteration is located in exon 10 (coding exon 8) of the LARP1B gene. This alteration results from a C to G substitution at nucleotide position 997, causing the proline (P) at amino acid position 333 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
