The c.431T>C (p.L144S) alteration is located in exon 3 (coding exon 2) of the HYKK gene. This alteration results from a T to C substitution at nucleotide position 431, causing the leucine (L) at amino acid position 144 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
