The c.743T>C (p.I248T) alteration is located in exon 7 (coding exon 7) of the HSDL2 gene. This alteration results from a T to C substitution at nucleotide position 743, causing the isoleucine (I) at amino acid position 248 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
