The c.2344A>T (p.M782L) alteration is located in exon 6 (coding exon 5) of the SUGP2 gene. This alteration results from a A to T substitution at nucleotide position 2344, causing the methionine (M) at amino acid position 782 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
