Collection Method: clinical testing

The c.289G>A (p.A97T) alteration is located in exon 2 (coding exon 2) of the HHIPL1 gene. This alteration results from a G to A substitution at nucleotide position 289, causing the alanine (A) at amino acid position 97 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
