The c.661G>T (p.D221Y) alteration is located in exon 4 (coding exon 4) of the HEPHL1 gene. This alteration results from a G to T substitution at nucleotide position 661, causing the aspartic acid (D) at amino acid position 221 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
