The c.2771C>T (p.S924L) alteration is located in exon 22 (coding exon 22) of the R3HDM2 gene. This alteration results from a C to T substitution at nucleotide position 2771, causing the serine (S) at amino acid position 924 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
