Collection Method: clinical testing

The c.1681T>C (p.Y561H) alteration is located in exon 5 (coding exon 4) of the KLHL28 gene. This alteration results from a T to C substitution at nucleotide position 1681, causing the tyrosine (Y) at amino acid position 561 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
