The c.182A>T (p.Q61L) alteration is located in exon 2 (coding exon 1) of the PSD4 gene. This alteration results from a A to T substitution at nucleotide position 182, causing the glutamine (Q) at amino acid position 61 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
