The c.742C>T (p.H248Y) alteration is located in exon 7 (coding exon 7) of the KLHL2 gene. This alteration results from a C to T substitution at nucleotide position 742, causing the histidine (H) at amino acid position 248 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
