Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.157C>T (p.R53C) alteration is located in exon 7 (coding exon 1) of the HNRNPA1L2 gene. This alteration results from a C to T substitution at nucleotide position 157, causing the arginine (R) at amino acid position 53 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
