The c.587C>A (p.T196K) alteration is located in exon 5 (coding exon 4) of the C12orf42 gene. This alteration results from a C to A substitution at nucleotide position 587, causing the threonine (T) at amino acid position 196 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
