Collection Method: clinical testing

The c.137T>A (p.M46K) alteration is located in exon 7 (coding exon 1) of the HNRNPA1L2 gene. This alteration results from a T to A substitution at nucleotide position 137, causing the methionine (M) at amino acid position 46 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
