The c.272A>T (p.Q91L) alteration is located in exon 5 (coding exon 5) of the IQCE gene. This alteration results from a A to T substitution at nucleotide position 272, causing the glutamine (Q) at amino acid position 91 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
