Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.61G>A (p.A21T) alteration is located in exon 2 (coding exon 1) of the CLUL1 gene. This alteration results from a G to A substitution at nucleotide position 61, causing the alanine (A) at amino acid position 21 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
