The c.740C>T (p.A247V) alteration is located in exon 8 (coding exon 8) of the EQTN gene. This alteration results from a C to T substitution at nucleotide position 740, causing the alanine (A) at amino acid position 247 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
