The c.1271C>A (p.A424D) alteration is located in exon 11 (coding exon 10) of the SAMD14 gene. This alteration results from a C to A substitution at nucleotide position 1271, causing the alanine (A) at amino acid position 424 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
