Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.61C>A (p.P21T) alteration is located in exon 1 (coding exon 1) of the HHIPL1 gene. This alteration results from a C to A substitution at nucleotide position 61, causing the proline (P) at amino acid position 21 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
