The c.361C>T (p.P121S) alteration is located in exon 2 (coding exon 2) of the STARD7 gene. This alteration results from a C to T substitution at nucleotide position 361, causing the proline (P) at amino acid position 121 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
