Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.35G>C (p.R12T) alteration is located in exon 1 (coding exon 1) of the LIN7C gene. This alteration results from a G to C substitution at nucleotide position 35, causing the arginine (R) at amino acid position 12 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
