Nov 23, 2024

The c.257C>T (p.A86V) alteration is located in exon 1 (coding exon 1) of the ABHD17C gene. This alteration results from a C to T substitution at nucleotide position 257, causing the alanine (A) at amino acid position 86 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
