Collection Method: clinical testing

The c.164T>G (p.L55R) alteration is located in exon 5 (coding exon 2) of the CEP57L1 gene. This alteration results from a T to G substitution at nucleotide position 164, causing the leucine (L) at amino acid position 55 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
