Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.92C>A (p.P31H) alteration is located in exon 1 (coding exon 1) of the LSR gene. This alteration results from a C to A substitution at nucleotide position 92, causing the proline (P) at amino acid position 31 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
