Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.221T>C (p.V74A) alteration is located in exon 2 (coding exon 1) of the LSM10 gene. This alteration results from a T to C substitution at nucleotide position 221, causing the valine (V) at amino acid position 74 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
