Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1001T>C (p.L334P) alteration is located in exon 8 (coding exon 8) of the GOT1L1 gene. This alteration results from a T to C substitution at nucleotide position 1001, causing the leucine (L) at amino acid position 334 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
