The c.1595T>A (p.M532K) alteration is located in exon 1 (coding exon 1) of the CD248 gene. This alteration results from a T to A substitution at nucleotide position 1595, causing the methionine (M) at amino acid position 532 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
