The c.881C>T (p.P294L) alteration is located in exon 6 (coding exon 6) of the HS1BP3 gene. This alteration results from a C to T substitution at nucleotide position 881, causing the proline (P) at amino acid position 294 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
