The c.290C>T (p.S97F) alteration is located in exon 2 (coding exon 1) of the HYKK gene. This alteration results from a C to T substitution at nucleotide position 290, causing the serine (S) at amino acid position 97 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
