The c.603C>A (p.N201K) alteration is located in exon 7 (coding exon 6) of the BABAM1 gene. This alteration results from a C to A substitution at nucleotide position 603, causing the asparagine (N) at amino acid position 201 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
