Genes affected

LMCD1 (HGNC:6633): (LIM and cysteine rich domains 1) This gene encodes a member of the LIM-domain family of zinc finger proteins. The encoded protein contains an N-terminal cysteine-rich domain and two C-terminal LIM domains. The presence of LIM domains suggests involvement in protein-protein interactions. The protein may act as a co-regulator of transcription along with other transcription factors. Alternate splicing results in multiple transcript variants of this gene. [provided by RefSeq, May 2013]

LMCD1-AS1 (HGNC:44477): (LMCD1 antisense RNA 1)

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.976

The c.485C>T (p.P162L) alteration is located in exon 4 (coding exon 4) of the LMCD1 gene. This alteration results from a C to T substitution at nucleotide position 485, causing the proline (P) at amino acid position 162 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
