Collection Method: clinical testing

The c.836G>A (p.R279H) alteration is located in exon 11 (coding exon 8) of the CEP57L1 gene. This alteration results from a G to A substitution at nucleotide position 836, causing the arginine (R) at amino acid position 279 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
